I wrote code for sinx But it is showing output as INF Why INF?? what's wrong with code .... plz help Code: #include<stdio.h> #include<math.h> int main() { float x,t=0,sum; int i,n,sig=1; printf("Input X,N"); scanf("%f %d",&x,&n); x*=(3.14/180); sum=x; for(i=0;i<n;i++) { sig*=-1; t=(sig*x*x)/(2*i*(2*i+1)); sum+=t; } printf("SIN(X) = %f\n",sum); return 0; } :snore:

In you code you are using the for loop that starts from zero. Code: for(i=0;i<n;i++) So when the loop runs for the first time, you get infinite in the variable t and you sum become infinite. Code: t=(sig*x*x)/(2*i*(2*i+1));z Whatever you add to Infinite, the result will be infinite Start your loop from 1 (ie for(i=1;i<n;i++)
