[cas] use of functions hyperbolic secant and cosecant and inverses
why not to included the hyperbolic secant and cosecant and inverses?
high school algebra books and first levels of engineering the show. these elementary functions must be in the system built-in. that you think, are important SECH() and CSECH() in engineering and education? other CAS include them, why not xcas? It would also allow display outputs rewritten or simplified https://www.wolframalpha.com/input/?i=di...h(x%2F2))) with SECH() and CSECH() diff (2* atan(tanh(x/2))) -> sech(x) int(sech(x)) -> (2* atan(tanh(x/2))) current CAS, WITHOUT SECH() and CSECH() diff (2* atan(tanh(x/2))) -> (-tanh((x/2))^2+1)/(tanh((x/2))^2+1) more info WIKIPEDIA Inverse hyperbolic function https://en.wikipedia.org/wiki/Inverse_hy...c_function |
