sin, sinf, sinh, sinhf
Calculate sines and hyperbolic sines.
double sin( double x ); float sin( float x ); // C++ only long double sin( long double x ); // C++ only float sinf( float x ); double sinh( double x ); float sinh( float x ); // C++ only long double sinh( long double x ); // C++ only float sinhf( float x );
sin returns the sine of x. If x is greater than or equal to 263, or less than or equal to –263, a loss of significance in the result occurs
sinh returns the hyperbolic sine of x. If the result is too large, sinh sets errno to ERANGE and returns ±HUGE_VAL, by default.
