Since I never paid much attention in Math and have nothing to compare it to, just wanted to make sure I had the fairly simple challenge in chapter 6 correct:

[code]#include <stdio.h>

#include <math.h>

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

{

```
printf("the sine of 1 radian is: %.3f", sin(1));
return 0;
```

}[/code]

(gives an output of: the sine of 1 radian is: 0.841)
