TAN(3)			 BSD Library Functions Manual			TAN(3)

NAME
     tan — tangent function

SYNOPSIS
     #include <math.h>

     double
     tan(double x);

     long double
     tanl(long double x);

     float
     tanf(float x);

DESCRIPTION
     The tan() function computes the tangent of x (measured in radians).

SPECIAL VALUES
     tan(�0) returns �0.

     tan(�infinity) returns a NaN and raises the "invalid" floating-point
     exception.

VECTOR OPERATIONS
     If you need to apply the tan() function to SIMD vectors or arrays, using
     the following functions provided by the Accelerate.framework may give
     significantly better performance:

     #include <Accelerate/Accelerate.h>

     vFloat vtanf(vFloat x);
     void vvtanf(float *y, const float *x, const int *n);
     void vvtan(double *y, const double *x, const int *n);

SEE ALSO
     acos(3), asin(3), atan(3), atan2(3), cos(3), cosh(3), sin(3), sinh(3),
     tanh(3), math(3)

STANDARDS
     The tan() function conforms to ISO/IEC 9899:2011.
