    //You are given the following mathematical expression: ....

//The sin(x) is a trigonometric function that returns the sine from the angle x (measured in radians).
//The mod operator finds the remainder of division of one number by another.
//Here are some examples for how the mod operator should work:
//•   5 mod 2 = 1
//•   5.99 mod 3 = 2
//•   6 mod 3 = 0
//Your task is to write a computer program that calculates the result from the shown mathematical expression, depending on the values of the variables N, M and P.

    double N = double.Parse(Console.ReadLine()),
            M = double.Parse(Console.ReadLine()),
            P = double.Parse(Console.ReadLine()),
            result = 0.0,
            upperPart = 0.0,
            downPart = 0.0,
            sinPart = 0.0;

    upperPart = N * N + (1 / (M * P)) + 1337;
    downPart = N - (128.523123123d * P);

    sinPart = Math.Sin((int)M % 180); //The important part. The remainders should work as those for integers!!!

    result = upperPart / downPart + sinPart;

    Console.WriteLine("{0:F6}", result);
