Value of Sine using Recursion (Taylor's theorem)

Problem Statement
Write a c program to calculate the value of sin using recursion
first scan the number x and then calculate the value of sine series(using Taylor's series)

#include<stdio.h> float srs(float x,int i); float term(float x,int i); int main() { float x,y; int i; printf("enter the value of x\n"); scanf("%f",&x); i=1; y=srs(x,i); printf("the sum is equals to %f",y); return 0; } float srs(float x,int i) { float sum=0.0; float t; t= term(x,i); if(i%2==0&&t>(-.000001)) { return 0; } else if(i%2!=0&&t<(.000001)) { return 0; } else { sum=t+ srs(x,i+1); } return sum; } float term(float x,int i) { float tn; int h; tn=x; for(h=2;h<2*i;h++) { tn= (x*tn)/h; } if(i%2==0) { tn= tn*(-1.0); return tn; } else { return tn; } }
