Just remember your rules and use your textbook to practise them, sorry I can't offer more help than that, but if you get stuck on a question, if you post it here I'll try to help, and I'm sure others wouldn't mind helping you out either.

Same thing came to my mind too....

Back to what d_a_n_z originally asked:
It's a matter of practising different questions...the ones you're most likely to confuse when differentiating/integrating are the trig functions - other than that, I don't think you should have too many problems.

Here are some practice problems for you:
1. Differentiate x^2
2. Integrate x^2




Answers:
(1) 2x
(2) (x^3)/3 + k

Lol, my teacher says whenever the question has a "c" in it (i.e. cos), the answer will be "contrary" (which means opposite sign, according to him) - then he started singing that nursery rhyme, "Mary mary quite contrary... blah blah" and told us to remember it that way :p

:confused: - hmm, whatever works I guess :)
I just "anti-derive" in my head to figure it out, but then again I still make careless errors.

Is the imaginary unit i or j? It doesn't matter. Mathematics is based on context - usually not too heavily; just enough to ensure there's no ambiguity.

i just remember it as opposites:

ie. differentiation is making the power less and integration making the power more.

so a way to make it visually appealing would be:

integration --> adding to the power

differentiation --> subtracting the power

well as study can be applied, whatever works for ya mate!
