Question
Why bother struggling..
I spent 15 mins trying to understand how to do symbolic differentiation using the help files and some googling. I just wanted to check a correct differentiation, having spent money on Mathcad. Now I am sure it can do it, but it was not explicitly stated how to do diff, and all I could get was a repetition of the original function, which is no help at all. I went to wolfram alpha and got the anser in less than a minute. The writing is on the wall my friends....
