  1. just curious
  2. [11:25:00 AM] Himiko Werckmeister: what is ur math curriculum like in your grade?
  3. [11:25:32 AM] UnHolyAngelLord: what do you mean
  4. [11:25:45 AM] Himiko Werckmeister: Well
  5. [11:25:50 AM] Himiko Werckmeister: to put it more frankly
  6. [11:25:55 AM] Himiko Werckmeister: what are u guys learning rn?
  7. [11:26:20 AM] UnHolyAngelLord: well Idk what my grade is learning cause I am currently taking honors for my math
  8. [11:26:50 AM] Himiko Werckmeister: Cool
  9. [11:26:54 AM] Himiko Werckmeister: then in that case
  10. [11:27:03 AM] Himiko Werckmeister: wha are u learning in that class?
  11. [11:27:07 AM] Himiko Werckmeister: because if I am not busy
  12. [11:28:02 AM] Himiko Werckmeister: I am willing to help ur ass out
  13. [11:28:49 AM] UnHolyAngelLord: to be frank we just finished the chapter and took our test that I got a 90 on and we are learning something tomorrow
  14. [11:29:11 AM] Himiko Werckmeister: Hmm?
  15. [11:29:16 AM] Himiko Werckmeister: What is that chapter on?
  16. [11:29:45 AM] UnHolyAngelLord: complex equations like with a fraction in the demonator and numerator
  17. [11:30:09 AM] Himiko Werckmeister: uhh kk
  18. [11:30:17 AM] Himiko Werckmeister: that stuff looks easy as heck
  19. [11:30:23 AM] UnHolyAngelLord: I know
  20. [11:30:37 AM] UnHolyAngelLord: brb
  21. [11:30:40 AM] Himiko Werckmeister: kk
  22. [11:30:42 AM] Himiko Werckmeister: btw....
  23. [11:30:56 AM] Himiko Werckmeister: I feel that the your education system goes way too easy on you
  24. [11:31:11 AM] Himiko Werckmeister: like I feel the stuff in third year mathematics
  25. [11:31:15 AM] Himiko Werckmeister: can be taught in HS
  26. [11:31:40 AM] UnHolyAngelLord: well idk I just learn I never really cared
  27. [11:31:52 AM] *** Himiko Werckmeister auto facedesks ***
  28. [11:32:00 AM] Himiko Werckmeister: Alright....
  29. [11:32:07 AM] Himiko Werckmeister: did u cover polynomials yet?
  30. [11:32:32 AM] UnHolyAngelLord: yea beginning of the year last year
  31. [11:32:38 AM] Himiko Werckmeister: Ok
  32. [11:32:49 AM] Himiko Werckmeister: time for a little intellectual excercise
  33. [11:32:58 AM] Himiko Werckmeister: we all know in math class
  34. [11:33:09 AM] Himiko Werckmeister: if we want to find roots of a quadratic....
  35. [11:33:18 AM] Himiko Werckmeister: we deploy the quadratic formula
  36. [11:33:24 AM] Himiko Werckmeister: however for higher degree polynomials
  37. [11:33:31 AM] Himiko Werckmeister: such an approach isn't feasible
  38. [11:33:34 AM] Himiko Werckmeister: now my question to u is....
  39. [11:33:49 AM] Himiko Werckmeister: how would u find the roots of an nth degree polynomial?
  40. [11:34:00 AM] Himiko Werckmeister: where n > 4
  41. [11:34:25 AM] UnHolyAngelLord: shit you are telling me to remember give me a minute
  42. [11:34:50 AM] Himiko Werckmeister: kk
  43. [11:35:26 AM] Himiko Werckmeister: js I only need like accuracy to 4 decimal places
  44. [11:42:02 AM] Himiko Werckmeister: tell me when ur done
  45. [11:43:10 AM] Himiko Werckmeister: Factor the polynomial....
  46. [11:43:29 AM] Himiko Werckmeister: x^4+5*x^3+2
  47. [11:43:44 AM] Himiko Werckmeister: Err I mean.....
  48. [11:43:50 AM] Himiko Werckmeister: find the zeros of it
  49. [11:44:57 AM] UnHolyAngelLord: fuck zeros is what screwed me over
  50. [11:45:13 AM] *** Himiko Werckmeister laughs extremely hard ***
  51. [11:45:21 AM] Himiko Werckmeister: Okk, calm urself down
  52. [11:45:32 AM] Himiko Werckmeister: allow me to present you something
  53. [11:45:39 AM] Himiko Werckmeister: that your teachers will never tell you
  54. [11:45:45 AM] Himiko Werckmeister: because they don't want you to know
  55. [11:46:04 AM] UnHolyAngelLord: what
  56. [11:46:12 AM] Himiko Werckmeister: What you essentially do.....
  57. [11:46:30 AM] Himiko Werckmeister: is pick any two initial estimates
  58. [11:46:39 AM] Himiko Werckmeister: then run the Bisection method on it
  59. [11:47:03 AM] UnHolyAngelLord: Bisection? I didn't learn that?
  60. [11:47:09 AM] Himiko Werckmeister: Welps
  61. [11:47:16 AM] Himiko Werckmeister: that should have been taught in high school
  62. [11:47:19 AM] Himiko Werckmeister: the main idea is....
  63. [11:47:23 AM] Himiko Werckmeister: you run a binary search
  64. [11:47:28 AM] Himiko Werckmeister: to find the roots of any equation
  65. [11:47:46 AM] UnHolyAngelLord: ok
  66. [11:48:10 AM] UnHolyAngelLord: im really starting to hate math now @_@
  67. [11:48:14 AM] Himiko Werckmeister: https://en.wikipedia.org/wiki/Bisection_method
  68. [11:48:25 AM] Himiko Werckmeister: Uhh don't give up your hopes just yet
  69. [11:48:30 AM] Himiko Werckmeister: its not that bad
  70. [11:48:52 AM] UnHolyAngelLord: I used to like math 100% now gah I hate it
  71. [11:49:12 AM] Himiko Werckmeister: Geez
  72. [11:49:17 AM] Himiko Werckmeister: don't blame me
  73. [11:49:29 AM] Himiko Werckmeister: you can blame the education system for that
  74. [11:49:35 AM] UnHolyAngelLord: No I was hating since I took honors Geometry
  75. [11:49:40 AM] UnHolyAngelLord: last year
  76. [11:49:46 AM] Himiko Werckmeister: Ah I see
  77. [11:49:54 AM] Himiko Werckmeister: Geometry flipping sucks
  78. [11:50:07 AM] Himiko Werckmeister: I am better off solving stuff algebriacally
  79. [11:50:14 AM] UnHolyAngelLord: yep
  80. [11:50:19 AM] Himiko Werckmeister: Did I open ur mind?
  81. [11:50:26 AM] Himiko Werckmeister: *blow ur mind with the bisection thing
  82. [11:50:48 AM] UnHolyAngelLord: I barely understand but in terms off blowing my mind yes casue I am confused as fuck
  83. [11:50:54 AM] Himiko Werckmeister: and wait that wikipedia page is terrible
  84. [11:51:02 AM] Himiko Werckmeister: I'll link you to a youTube video
  85. [11:51:04 AM] Himiko Werckmeister: since....
  86. [11:51:09 AM] Himiko Werckmeister: fk reading textbooks
  87. [11:51:35 AM] UnHolyAngelLord: wait why am I doing polynomials I stopped that doing that stuff last you
  88. [11:51:37 AM] Himiko Werckmeister: https://www.youtube.com/watch?v=XPUsRgaMsUs
  89. [11:51:37 AM] UnHolyAngelLord: year
  90. [11:51:45 AM] Himiko Werckmeister: Well its for motivation purposes
  91. [11:51:52 AM] Himiko Werckmeister: to tell u all dirty little math secrets
  92. [11:52:01 AM] Himiko Werckmeister: that your teachers will never tell u
  93. [11:52:08 AM] UnHolyAngelLord: hm ok then
  94. [11:52:45 AM] Himiko Werckmeister: lets suppose a scenerio like this happens:
  95. [11:53:19 AM] Himiko Werckmeister: Your teacher makes you find zeros of a polynomail
  96. [11:53:30 AM] Himiko Werckmeister: and yes this will creep back up and haunt you
  97. [11:53:35 AM] UnHolyAngelLord: ugh
  98. [11:53:38 AM] Himiko Werckmeister: later in grade 12
  99. [11:53:44 AM] Himiko Werckmeister: when you are doing trig algerbra
  100. [11:53:47 AM] Himiko Werckmeister: and u go liek
  101. [11:53:50 AM] Himiko Werckmeister: FK FACTORING!
  102. [11:53:56 AM] Himiko Werckmeister: and you want a close estimate
  103. [11:53:56 AM] UnHolyAngelLord: I already say that
  104. [11:54:08 AM] UnHolyAngelLord: ive been doing factoring for a few months
  105. [11:54:13 AM] Himiko Werckmeister: then u just run any of the root finding method
  106. [11:54:33 AM] Himiko Werckmeister: Bisection is the most safe but very slow in terms of finding the root you want
  107. [11:54:45 AM] Himiko Werckmeister: Newton's Method [another root finding method]
  108. [11:55:02 AM] Himiko Werckmeister: (Note: you would want to learn a bit about deriatives before diving in
  109. [11:55:06 AM] Himiko Werckmeister: (more on this latter
  110. [11:55:08 AM] Himiko Werckmeister: (*later
  111. [11:55:25 AM | Edited 11:55:57 AM] Himiko Werckmeister: May diverge if you select an intial estimate such that its deriative evaluates close to 0
  112. [11:56:02 AM] Himiko Werckmeister: but if you are lucky
  113. [11:56:08 AM] Himiko Werckmeister: its relatively efficient
  114. [11:56:18 AM] Himiko Werckmeister: in terms of findng the root you want
  115. [11:56:34 AM] Himiko Werckmeister: (btw feel free to ask any questions and interrupt me
  116. [11:56:51 AM] Himiko Werckmeister: And ofc we cannot forget about False Position or Secant method
  117. [11:57:19 AM] UnHolyAngelLord: gah all this information is gonna be in my head while I learn new stuff tomorrow
  118. [11:58:18 AM] Himiko Werckmeister: hm?
  119. [11:58:21 AM] Himiko Werckmeister: what is this new stuff?
  120. [11:58:40 AM] UnHolyAngelLord: I learn new stuff in math literally tomorrow but this is gonna be in my head
  121. [11:59:08 AM] Himiko Werckmeister: alright...
  122. [11:59:23 AM] Himiko Werckmeister: use the root finding methods I just described
  123. [11:59:30 AM] UnHolyAngelLord: ok
  124. [11:59:30 AM] Himiko Werckmeister: if you want to make your friends jealours
  125. [11:59:36 AM] UnHolyAngelLord: understood
  126. [11:59:44 AM] Himiko Werckmeister: or next time you get a polynomial quesiton
  127. [11:59:51 AM] Himiko Werckmeister: and if the teacher marks the question wrong
  128. [11:59:53 AM] Himiko Werckmeister: complain
  129. [12:00:29 PM] UnHolyAngelLord: ok
  130. [12:00:30 PM] Himiko Werckmeister: Sayy.....
  131. [12:00:43 PM] Himiko Werckmeister: did you guys learn linear systems in school yet?
  132. [12:00:56 PM] UnHolyAngelLord: I think but I don't know for sure
  133. [12:01:03 PM] Himiko Werckmeister: Yosh
  134. [12:01:09 PM] Himiko Werckmeister: another dirty little secret
  135. [12:01:15 PM] Himiko Werckmeister: that your teachers will never ever tell u
  136. [12:01:40 PM] Himiko Werckmeister: your teachers may ask you to solve the system by manual elimination
  137. [12:01:43 PM] Himiko Werckmeister: but....
  138. [12:01:50 PM] Himiko Werckmeister: in fact there is something much slicker
  139. [12:02:22 PM] Himiko Werckmeister: http://www.purplemath.com/modules/systlin6.htm
  140. [12:02:31 PM] Himiko Werckmeister: ^You deploy Gaussian Elimination
  141. [12:02:57 PM] Himiko Werckmeister: or.... if you just want your answer to five decimal places (again ur teacher might ask for thhat)
  142. [12:03:10 PM] UnHolyAngelLord: ok
  143. [12:03:18 PM] Himiko Werckmeister: You deploy Gauss-Seidal iteration
  144. [12:03:29 PM] Himiko Werckmeister: Jacobi Iteration
  145. [12:03:40 PM] Himiko Werckmeister: or SOR [Succesive over relaxation]
  146. [12:03:50 PM] UnHolyAngelLord: hm ok then
  147. [12:04:01 PM] Himiko Werckmeister: Again another tool to make your friends jealous
  148. [12:04:12 PM] Himiko Werckmeister: and also make it easier for your teacher to mark ur shit
  149. [12:04:24 PM] Himiko Werckmeister: just know some matrix algerbra basics
  150. [12:04:28 PM] Himiko Werckmeister: and your set
  151. [12:04:36 PM] UnHolyAngelLord: hm ok then thanks
  152. [12:05:11 PM] Himiko Werckmeister: no problems
  153. [12:05:28 PM] Himiko Werckmeister: those stuff isn't taught until third year math
  154. [12:05:35 PM] UnHolyAngelLord: ah ok
  155. [12:05:45 PM] Himiko Werckmeister: and now you think of it....
  156. [12:05:48 PM] Himiko Werckmeister: that makes me angry
  157. [12:06:01 PM] Himiko Werckmeister: do u understand part of the video I linked u?
  158. [12:06:44 PM] UnHolyAngelLord: im on phone at the moment it doesn't open links im gonna watch it later
  159. [12:06:56 PM] Himiko Werckmeister: alright
  160. [12:07:01 PM] Himiko Werckmeister: let me know if anything confuses you
  161. [12:07:05 PM] UnHolyAngelLord: ok
  162. [12:07:16 PM] Himiko Werckmeister: now are u mind blown now?
  163. [12:07:46 PM] UnHolyAngelLord: yes
  164. [12:07:52 PM] Himiko Werckmeister: hehe
  165. [12:08:04 PM] Himiko Werckmeister: at this rate....
  166. [12:08:10 PM] Himiko Werckmeister: you may know more math
  167. [12:08:12 PM] Himiko Werckmeister: than your math teacher
  168. [12:08:28 PM] UnHolyAngelLord: ha maybe
  169. [12:10:17 PM] Himiko Werckmeister: At any rate
  170. [12:10:26 PM] Himiko Werckmeister: from looking at what you learnt just now
  171. [12:10:37 PM] Himiko Werckmeister: you should be able to teach yourself calculus
  172. [12:10:46 PM] UnHolyAngelLord: hm ok
  173. [12:10:55 PM] Himiko Werckmeister: its not that bad
  174. [12:11:04 PM] Himiko Werckmeister: I started teaching myself that stuff in grade 1
  175. [12:11:06 PM] Himiko Werckmeister: *10
  176. [12:11:14 PM] Himiko Werckmeister: Three main ideas
  177. [12:11:16 PM] Himiko Werckmeister: Limits
  178. [12:11:19 PM] Himiko Werckmeister: Deriatives
  179. [12:11:23 PM] Himiko Werckmeister: and Intergrals
  180. [12:11:40 PM] Himiko Werckmeister: main idea to take away for each
  181. [12:11:52 PM] Himiko Werckmeister: Limit- as x approaches a specific value
  182. [12:12:03 PM] Himiko Werckmeister: what value of y does it arbitarily approach to?
  183. [12:12:10 PM] Himiko Werckmeister: Deriatives- you find a slope of a function
  184. [12:12:13 PM | Edited 12:12:52 PM] Himiko Werckmeister: simple as that
  185. [12:12:17 PM] Himiko Werckmeister: Intergrals
  186. [12:12:24 PM] Himiko Werckmeister: u find an area under a curve
  187. [12:13:04 PM] UnHolyAngelLord: hm ok
  188. [12:13:35 PM] Himiko Werckmeister: Main half assed mistakes ppl make
  189. [12:13:42 PM] Himiko Werckmeister: its all about the Algerbra
  190. [12:13:58 PM] UnHolyAngelLord: ok
  191. [12:15:16 PM] Himiko Werckmeister: Once u learn a bit about differential equations
  192. [12:15:27 PM] Himiko Werckmeister: I can teach you some techniques
  193. [12:15:43 PM] Himiko Werckmeister: on finding approximate solutions to them
  194. [12:15:50 PM] UnHolyAngelLord: hm ok
  195. [12:16:11 PM] Himiko Werckmeister: I think you have potential to learn some of this supposedly hard stuff
  196. [12:16:20 PM] Himiko Werckmeister: so I consider u my fellow skype buddy and student
  197. [12:16:59 PM] UnHolyAngelLord: ok smiles
