Explanation |
|
atan() is a Mathematical Function that returns the arc tangent for the given argument.
Syntax to find Arc Tangent Value
float atan ( float arg );
double atan ( double arg );
long double atan ( long double arg );
Example:
#include <iostream.h>
#include <cmath.h>
int main ()
{
cout << "Arc Tangent value of .5 is :: " << atan(.5) ;
return 0;
}
|
Result:
Arc Tangent value of .5 is :: 0.463648
In the above example atan() is used to find the arc tangent value for ".5".
