комплексный арксинус гиперболический (complex arc sine hyperbolic)
Имя (Name)
casinh, casinhf, casinhl - complex arc sine hyperbolic
Синопсис (Synopsis)
#include <complex.h>
double complex casinh(double complex z);
float complex casinhf(float complex z);
long double complex casinhl(long double complex z);
Link with -lm.
Описание (Description)
These functions calculate the complex arc hyperbolic sine of z.
If y = casinh(z), then z = csinh(y). The imaginary part of y is
chosen in the interval [-pi/2,pi/2].
One has:
casinh(z) = clog(z + csqrt(z * z + 1))
Версии (Versions)
These functions first appeared in glibc in version 2.1.
