I'm trying to integrate 'e^(-B*x^2) from -inf to +inf' with the hp prime emulator. The calculator is not spitting out what I'm looking for which is sqrt(pi/B) and incorrectly gives infinity as the answer.
However, it gives the correct answer (sqrt(pi)) when I just integrate 'e^(-x^2) from -inf to +inf' (without any letters). If I use a number instead of a letter, then it starts giving out the correct answer again. I'm completely new to the prime (currently have a 50G) so can anyone tell me how to get my answer in terms of the letter?
