50g

I set the step by step flag, but hitting eval just gives me a the final solution.

- Any tips?

Oh yea and I am returning to study this year so I am going to be asking plenty of questions.

Step by step only works for a few things. Symbolic integration, sym diff, linear system solving. . . any others?

Thanks Tim, could you refresh me on how symbolic integration works
again?

I tried this but it comes up invalid argument.

Thanks Mick

You should have 'S(0,T,X^2,X)' on the stack, if pretty print is turned off.

If you don't want to use "functional notation", your stack can look like...

0
T
X^2
X

...then hit the integrate key.

Also, make sure you're in exact mode.
