I can't see what you have done but, it doesn't look like you have integrated by parts.

Oh, I missed that integration lesson, when do you integrate by parts, is it when you have to integrate a product so in this case 960t * Sin2t

I tried to just integrate it just using integral of y dx/dt which I know lel

Basically get the chain rule and reverse it, integrate both sides and use that to find these types of integrals. Yes when using two functions of t. Like say if it was t(t-1)^2 u could use it but there is no point as you can expand that and integrate. Have a look at integration by parts.

The funny thing is, we have nearly finished C4 now. We have all of chapter 5 and exercise 6G onwards to complete for chapter 6.
So we've done like half of chapter 6. Should take us 2 more weeks probably to finish.

Yeah I know. We started c3 after our AS exams last year. Then we started c4 in November and finished in December. I have two teachers and they feel as though they have to rush through the syllabus and finish ASAP to have more time for tests and revision. Already started D1 think week!

I have never heard of a school finishing C4 or any modules in one month. Even if they're going to focus on exam and revision if i don't get the content right I'll be struggling through all y papers.

I know someone who's teacher had at least a masters and was the only teacher whom she called a 'genius' amongst her others with phd's (not sure if true anyways 'don' is better and less embarrassing/silly term lol considering their just normal ppl. Writes papers for Oxbridge undergrad or something like that.
My guy is all-right I suppose.
ima still do m2 in 2 weeks though :P
