C program to compute sin(x) using Taylor’s series

C program to compute sin(x) using Taylor’s series: In this program we will use taylor series to compute sin(x), code for the problem is given below.

Code for C program to compute sin(x) using Taylor’s series

#include <stdio.h>
#include <math.h>
int main()
{
  float fact(float);
  float sum = 0, x, range;
  int i, j;
  printf("Enter the X value:");
  scanf("%f", &x);
  x = x * 3.14 / 180.0;
  printf("Enter the range value:");
  scanf("%f", &range);
  for (i = 1, j = 1; i <= range; i++, j = j + 2)
  {
    if (i % 2 != 0)
      sum = sum + pow(x, j) / fact(j);
    else
      sum = sum - pow(x, j) / fact(j);
  }
  printf("%f", sum);
}
float fact(float x)
{
  int f = 1, i;
  for (i = 1; i <= x; i++)
    f = f * i;
  return f;
}
