JavaScript help...

I have been learning the language JavaScript for a while. I recently decided to try and make my own method to return Sine of a double as a double. I am trying to use a taylor series centered at 0, but 0.0 keeps getting returned. Could anyone help me?

Note : NumbertoPower() and FactorialSimple() are other funcions of my own creation that do what thier signiture implies.

public static double SinetoDegree5(double num1)
{

while(num1 > Math.PI / 2)
num1 = num1 - Math.PI;

while(num1 < -1 * Math.PI / 2)
num1 = num1 + Math.PI;

int step = 1;
int sign = 1;
double base = 0;
while(step <= 9)
{
base = base + (NumbertoPower(base, step) / FactorialSimple(step));

if(sign == 1)
sign = -1;
else
sign = 1;

step = step + 2;
}
return base;

}

base = base + (NumbertoPower(num1, step) / FactorialSimple(step))*sign;

num1 = num1 % Math.PI; instead of the first crap

you mean JAVA right? not javascript?

This code looks similar to calculator code...

interesting.

Does Java run on linear based commands or different section type deals?

The Taylor series for Sine is is...



I am trying to implement the first 3 terms in the seres...


Am I missing something / could you elaborate
