Think how I feel when I do FP3 vectors!

Integration can just go and get ****ed, the worthless piece of ****. Absolutely hate it, integration by substitution is an absolute bastard of a topic to learn.

Why so? It's all about bringing together what you already know, like the chain rule, trig identities, and standard integrals

With vectors drawing a clear labelled diagram helps a lot spotting what you have to do

I can just imagine the uproar if the vectors from FP3 were added to C4 :colone:

Integration you'll be able to spot what method to use with practice, vectors you have to make sure you understand conceptually otherwise you won't even be able to attempt a question out of the ordinary in a paper.

Integration is easy in the exams because you can always get your calculator to check it. Well after doing FP3 vectors, C4 vectors are so easy. Do all the questions in the textbook and you should be fine.

I used to hate vectors, but now if I take my time with it, it just feels like working out intersections in C1 but with added elements of glorified Pythagoras.

But yeah integration can go and ****ing burn in a pit of boiling tar.

How can you check you have integrated correctly with a calculator?

Some calculators have an integration function. Mine does

yeah thats what i struggle with haha, although im getting better at it now! those differential equations still catch me out time to time, not solving them, but more when the question asks you to form one, just can't get my head around that! Weirdly i find C4 vectors easier than M1 vectors haha

Probably some of the most autistic posts I've ever seen.

Kudos.

(b) Hence, or otherwise, ﬁnd the ﬁrst three terms in the expansion of 5x

Did an Elmwood paper and when it said 'fire three terms' I just went up to x^2, but the MS went up to x^3. Does 'terms' mean power of x?

Paper or mark scheme could be wrong. Any chance of the full question?

Correct me if I'm wrong but I think because it says in ascending powers of x so you go up to x^3 not including the one because it doesn't have x so it doesn't count

I wasn't sure. Is that how you tell?
