sinh

Related functions are asin( ), acos( ), atan2( ), atan( ), tan( ), cos( ), sinh( ), cosh( ), and tanh( ).

#include <cmath> float sinh(float arg); double sinh(double arg); long double sinh(long double arg);

sqrt

The sinh( ) function returns the hyperbolic sine of arg.

Related functions are asin( ), acos( ), atan2( ), atan( ), tan( ), cos( ), tanh( ), cosh( ), and sin( ).

#include <cmath> float sqrt(float num); double sqrt(double num); long double sqrt(long double num);

tan

The sqrt( ) function returns the square root of num. If it is called with a negative argument, a domain error will occur.

Related functions are exp( ), log( ), and pow( ).

#include <cmath> float tan(float arg); double tan(double arg); long double tan(long double arg);

The tan( ) function returns the tangent of arg. The value of arg must be in radians.

Related functions are acos( ), asin( ), atan( ), atan2( ), cos( ), sin( ), sinh( ), cosh( ), and tanh( ).
