Remind yourself that c3 is worse than c4 and once you've done c3 revision you can revise/do an easier paper, aka c4 :wink:

Im starting c3 on Monday

Our teacher gave us this question a while back...I quite liked it.

I thought people here may like to see it/have a go. :smile:

\displaystyle\int e^{3x} \cos(2x) dx

Leave answers in spoilers so that others can have a go if they want to. :smile:

My teacher gave me a question like that (but with different numbers). It took me about an hour (during my free period) to notice what I was meant to do! I got it in the end though :tongue:

Hmm...would a question like that ever come up in an exam? :holmes:

If so, how many marks do you think it'd be? :tongue:

I guess it took us about four lessons. Our teacher just made a booklet with the different types of questions they can ask and we worked through those for our teaching of the vectors chapter. There isn't really that much in it (although I still don't like them).

Were they textbook questions or past paper questions in the booket? so you started past/solomon papers ?

I'm not sure. I'm guessing textbook or made up as some of the first ones were really basic (to introduce us to it) and I can't imagine they would have come up in an exam. I've done one past paper and one solomon paper. Although I still need to look over the factor formulae (trigonometry) as I didn't do them properly in C3 and you need them to integrate some things.
