Predefined Functions - cosh
Description: ChaosPro automatically detects the input data type. In order to calculate cosh(x) (x = any real number) ChaosPro performs the following calculation: cosh (x) = 0.5 * ( exp(x) + exp(-x) ) In order to calculate cosh(z) (z = any complex number) ChaosPro performs the following calculation: cosh(z)=cosh(x)*cos(y)+i*sinh(x)*sin(y) where sinh(x) (x = any real number) is defined as: sinh(x) = 0.5 * ( exp(x) - exp(-x) ) |
