Defined in header `<cmath>`

float tan( float arg );

double tan( double arg );

long double tan( long double arg );

double tan( Integral arg );		(since C++11)

Computes tangent of arg.

arg

-

value representing angle in radians, of a floating-point or Integral type

Tangent of arg.

Domain error occurs if arg is infinite. NAN is returned in that case.
