sin()
The sin()
function returns the sine of an angle argument, given in radians, in the range [-1,1].
Syntax
sin(angle)
The angle
parameter is expressed in radians.
Example
The following example illustrates the sin()
function:
#include<iostream>#include<math.h>using namespace std;int main() {// convert degrees to radiansdouble pi = M_PI;double degree = 60;double radian = degree * pi/180;cout << "Sine of 60 degrees is " << sin(radian) << "\n";return 0;}
This results in the following output:
Sine of 60 degrees is 0.866025
