ctan(3) Library Functions Manual ctan(3) NAME ctan, ctanf, ctanl - complex tangent function LIBRARY Math library (libm, -lm) SYNOPSIS #include double complex ctan(double complex z); float complex ctanf(float complex z); long double complex ctanl(long double complex z); DESCRIPTION These functions calculate the complex tangent of z. The complex tangent function is defined as: ctan(z) = csin(z) / ccos(z) ATTRIBUTES For an explanation of the terms used in this section, see attributes(7). +--------------------------------------------+---------------+---------+ |Interface | Attribute | Value | +--------------------------------------------+---------------+---------+ |ctan (), ctanf (), ctanl () | Thread safety | MT-Safe | +--------------------------------------------+---------------+---------+ STANDARDS C11, POSIX.1-2008.
