Another xCAS commands > Prime. discussion
Hi HPPrime Team, sorry for the electronic translation
There is a command that is not included in the latest firmware version. with_sqrt (True / False) it's a flag type cmd for factored in terms of irreducible factors with respect to the rational numbers. (In other words, none of the polynomials in the factored form can be factored further without introducing radicals.) The idea is to work with the command line in the history view without going to the configuration view, for this reason, HPPrime Team must include with_sqrt(True / False) in the next firmware improvements sentences to enter the history view to observe the operation of with_sqrt () PHP Code: with_sqrt( False ); [enter] 0 https://tiplanet.org/forum/portal.php

Hello, In the symbolic environment CAS, the following mathematical expression should return euler_gamma constant
limit(Σ(1/k,k,1,n)ln(n),n, +infinity) [enter] 0.577215664902 // current hpprime limit(Σ(1/k,k,1,n)ln(n),n, +infinity) [↵] returns euler_gamma // Xcas for which it is required to add the constant euler_gamma in a future version euler_gamma [↵] Xcas returns euler_gamma evalf(euler_gamma) [↵] Xcas returns 0.577215664902 %gamma > 0.577215664902 // MAXIMA CAS Frn info. > https://wwwfourier.ujfgrenoble.fr/~par...tml#sec201 Eng info. > https://wwwfourier.ujfgrenoble.fr/~par...node4.html Spn info > http://www.eonicasys.com/CAS/xcas/cascmd...d_xcas.txt https://tiplanet.org/forum/portal.php
