To solve this equation, we can try to manipulate it into a more manageable form. Let's recall some useful trigonometric identities:
1. $\sin^2(x) + \cos^2(x) = 1$
Since both $\sin(x)$ and $\cos(x)$ in the original equation are raised to odd powers, it might be helpful to try to reduce these powers.
We are given:
$\sin^{11}(x) + \cos^{11}(x) = 1$
Let's multiply both sides by $\sin^2(x) + \cos^2(x)$ = 1. This gives:
$(\sin^{11}(x) + \cos^{11}(x))(\sin^2(x) + \cos^2(x)) = 1 \cdot (\sin^2(x) + \cos^2(x))$
Expanding the left-hand side:
$\sin^{13}(x) + \cos^2(x) \sin^{11}(x) + \sin^2(x) \cos^{11}(x) + \cos^{13}(x) = \sin^2(x) + \cos^2(x)$
We can rearrange this as:
$\sin^{13}(x) + \cos^{13}(x) = \sin^2(x) + \cos^2(x) - \cos^2(x) \sin^{11}(x) - \sin^2(x) \cos^{11}(x)$
$\sin^{13}(x) + \cos^{13}(x) = \sin^2(x)(1 - \cos^{11}(x)) + \cos^2(x)(1 - \sin^{11}(x))$
Hmm, this isn't reducing the powers as I had hoped. Let me try another approach.
I can use the identity $\sin^2(x) + \cos^2(x) = 1$ to rewrite the original equation:
$\sin^{11}(x) + \cos^{11}(x) = (\sin^2(x) + \cos^2(x))^5 \cdot (\sin(x) + \cos(x))$
Actually no, that's wrong. Sorry. Let's start over.

Let's manipulate the equation.

Recalling relevant trigonometric identities and facts.
1. $\sin^2(x) + \cos^2(x) = 1$
2. $\sin(x)$ and $\cos(x)$ in the original equation are raised to odd powers.

Let's try reducing these powers.
Starting with:
$\sin^{11}(x) + \cos^{11}(x) = 1$
Multiplying both sides by $\sin^2(x) + \cos^2(x)$ = 1:
$(\sin^{11}(x) + \cos^{11}(x))(\sin^2(x) + \cos^2(x)) = 1 \cdot (\sin^2(x) + \cos^2(x))$
Expanding the left-hand side:
$\sin^{13}(x) + \cos^2(x) \sin^{11}(x) + \sin^2(x) \cos^{11}(x) + \cos^{13}(x) = \sin^2(x) + \cos^2(x)$
Rearranging:
$\sin^{13}(x) + \cos^{13}(x) = \sin^2(x) + \cos^2(x) - \cos^2(x) \sin^{11}(x) - \sin^2(x) \cos^{11}(x)$
Rearranging:
$\sin^{13}(x) + \cos^{13}(x) = \sin^2(x)(1 - \cos^{11}(x)) + \cos^2(x)(1 - \sin^{11}(x))$
This doesn't help reducing these powers. Let's try something different.

Let's try using $\sin^2(x) + \cos^2(x) = 1$ to rewrite the equation.
$\sin^{11}(x) + \cos^{11}(x) = (\sin^2(x) + \cos^2(x))^5 \cdot (\sin(x) + \cos(x))$
This is wrong. Let's try something different.

This question is asking if a balloon made out of lead (Pb), rather than a typical material like latex or mylar, could float if it was filled with helium.
To determine if a lead balloon filled with helium could float, I'll need to:
1. Calculate the density of helium gas at room temperature
2. Calculate the required volume of helium for buoyancy
3. Given the density of lead, determine if it's physically possible to construct a lead balloon with a thickness that would allow the combined balloon and helium to be buoyant in air.
Let's start with the density of helium. Under standard conditions (room temperature and atmospheric pressure), helium has a density of about 0.1786 kg/m³.
Air, under the same conditions, has a density of about 1.225 kg/m³.
For a balloon to float, the combined weight of the balloon material and the helium inside must be less than the weight of the air displaced by the balloon.
The density of lead is about 11,340 kg/m³. Even if we could make an incredibly thin lead balloon, the weight of the lead would be enormous compared to the lifting capacity of the helium.
Let's imagine we make a spherical balloon with a radius of 1 meter. The volume of such a sphere is 4/3 x π x r³, which for r = 1 is about 4.19 m³.

Rephrasing the question:
Can a balloon made out of lead (Pb) float if it was filled with helium.

Planning:
1. Calculate the density of helium gas at room temperature
2. Calculate the required volume of helium for buoyancy
3. Given the density of lead, determine if it's physically possible

Let's calculate the density of helium gas at room temperature.
Under standard conditions (room temperature and atmospheric pressure), helium has a density of about 0.1786 kg/m³

Let's calculate the required volume of helium for buoyancy.
Under standard conditions (room temperature and atmospheric pressure), air has a density of about 1.225 kg/m³.
For a balloon to float, the combined weight of the balloon material and the helium inside must be less than the weight of the air displaced by the balloon.
Estimating the weight of the balloon material:
Lead has a density of about 11,340 kg/m³.
Observation: This is very large compared to what helium can usually lift. The lead balloon would have to be very thin.
Estimating the volume of the balloon:
Simplifying assumption: the balloon is a sphere with a radius $r$ of 1 meter.
The volume of a sphere is $4/3 \times \pi \times r^3$
Numerical computation: $4/3 \times \pi \times r^3 = 4/3 \times \pi \times 1^3 \approx 4.19$ The volume of the balloon is about $4.19 m^3$
