Ok, I love math, but I had to go back and review a little bit for this one.

First, you need to know that 1 Radian is appx 57.296 degrees.

Second, you need to know the code for pi in C is M_PI

Third, you need to know the formula for finding the Radian = Degrees * PI/180

## Got All that? Now here’s my Solution:

#include <stdio.h>

#include “math.h”

int main(int argc, const char * argv[])

{

float z = (57.296)*(M_PI/180);

printf(“The sine of 1 radian is %.3f\n”,sinf(z));

}

Hope This Helps!
