Writing C code for sin(x) using taylor series

[Ben Stone]

I am trying to write C code for sin(x) using the first 5 terms of the taylor series. I am new to programming and am not allowed to use loops. I don't have much yet, but what I have so far is:

/* solution to Taylor Series approximation of sin(x) */
#include <stdio.h>
#define PI 3.1416f

int main ()
{
float x_deg;
float x;
float sinx;

/*enter the angle "x_deg in degrees"*/
printf ("Enter x_deg:");
scanf ("%f, %x_deg);

x=x_deg*PI/180;

I am not really sure where to go from here. I am a little confused about how to implement the taylor series to calculate sin(x). Any help would be appreciated, thanks.

Perhaps you had better explain how the Taylor series is calculated, or rather what it is you want to calculate. We ar code gurus not maths gurus :D

You seem to have used the type float in your program but normally we would advise anyone using floating point types to use double unless they have a good and communicable reason why they need to use float.
