Problem with Laplace transform [SOLVED] - JMB - 11-12-2016 02:19 PM
The command laplace(SIN(t*pi/10)*(Heaviside(t)-Heaviside(t-10)),t,s) works correctly. [attachment=4139] Now if instead of the number 10 we use a constant (a), and execute the commands assume(a>0) and laplace(SIN(t*pi/a)*(Heaviside(t)-Heaviside(t-a)),t,s) , the result is not correct. [attachment=4141] It should be the same as in the first image, substituting a for 10 in the numerator, and a^2 for 100 in the denominator. The program XCAS gives correct answers in both cases.

The version of giac in the current firmware is older than in Xcas, a bug has certainly be fixed. RE: Problem with Laplace transform [SOLVED] - JMB - 02-02-2018 08:58 PM
Corrected in firmware 13333. Thanks to the HP Prime Team! |
