tan() - Mathematical Function

How is Mathematical Function "tan()" used in C++?
How to find the tangent value of an argument?


tan() is a Mathematical Function that returns the tangent value for the given argument, that is in radians.

Syntax to find Tangent value :

float tan( float arg);
double tan( double arg);
long double tan( long double arg);

Example :

#include <iostream.h>
#include <cmath.h>
int main()
cout << "The tangent of 60
is:: " << tan(60) <cout << "The tangent of 30
is:: " << tan(30) << endl;
return 0;

Result :

The tangent of 60 is:: 0.32004
The tangent of 30 is:: -6.40533

In the above example tan() is used to find tangent for the given arguments 60,30 degree radians.
