tan, tanf, tanh, tanhf
Visual Studio 2008
Calculate the tangent (tan or tanf) or hyperbolic tangent (tanh or tanhf).
double tan( double x ); float tan( float x ); // C++ only long double tan( long double x ); // C++ only float tanf( float x ); double tanh( double x ); float tanh( float x ); // C++ only long double tanh( long double x ); // C++ only float tanhf( float x );
