@S M Blinder. Thank you. That's what I am looking for.
Hello, Thank you for your reply. I am doing that to get steps for the solution.This way it only gave me the answer. Regards
Hello, Please, I used blow code to calculate **Ur**, which is derivative of **U** with respect to **y**. I got the result. The problem that when I try to integrate the result **Ur** with respect to **r** Mathematic failed to integrate. I tried to...
Show steps is a feature for Wolfram|Alpha. What you've given is code. Not input for Wolfram|Alpha. Are you using Wolfram|Alpha or Mathematica? You can't ask Mathematica to "show steps".
I was going to mention this. There are indeed two common conventions for the modulus parameter, and that does give rise to confusion.
You can use the Trace[] function to see intermediate steps in the evaluation of a Mathematica expression. I often find it more instructive to apply trace to individual parts of complicated expressions. This helps to simplify interpreting the results....
Hello, Thank you so much for all your help!
