Question

It is declared as: double sine(double X);

it will return the sine of X measured in radians. it will return the "double" value Not-A-Number for all error conditions. The value of sine is to be approximated using a power power series. Expand each power series approximation until you reach a term whose absolute value is less than a specified epsilon (1.0e-8). The term should not be included in the approximate value of the power series. This is what I have so far but it doesn't work, can anyone help? The power(...) and the factorial(...) are also functions I made but they work.

double sine(double X)

{

double Num;

double N;

double D;

double P;

double epsilon = 0.00000001;

if (X == 0)

{

Num = 0;

}

else

{

for (unsigned A=0; (power(X,2*A+1)/factorial(2*A+1)) > epsilon; A++)

{

N = power(-1,A);

D = factorial(2*A + 1);

P = power(X,2*A + 1);

Num = (N/D)*P;

}

return Num;

}
