Hello everyone, I wanted to know how I could calculate the following integral: integral from 0 to +∞ of sin (2t) * e^(st), where s is a complex number. Wolframalpha shows the correct result: https://www.wolframa...&t=crmtb01&f=rcthat is 2 / (s ^ 2 + 4). But if I input into the CAS of my calculator ∫ (sin (X) * eSX, X, 0, ∞), the calculator, after a little bit of time, show me "Undefined". How should I make my calculator calculate that integral as it already wolframalpha does , so I can get the Laplace transform? Alternatively, do you know any add-ins for calculating the Laplace transform? Thanks a lot to everyone in advance!
