Re: AQA MPC3 31/05/12 revision thread AQAOh that great(Original post by JulietheCat)
Yes, range is y and domain is x. The substitution with u^2, you just rearrange for x and diffrentiate it.
U^2=X-1
X=U^2+1
Diffrentiate the x function and since it is dx/du, you have to multiply the derivative (2U) by the function which you are trying to integrate. I had such questions in my textbook but never realised where I was going wrong! Now I know how to do it.
I will try it later on...
So,have you got any problem/unsure in C3 or just waiting for the exam?

Re: AQA MPC3 31/05/12 revision thread AQAI need to go through mid ordinate and Simpsons rule as I'm a little rusty. But as long as I don't make silly mistakes, I should be fine.(Original post by kenau)

Re: AQA MPC3 31/05/12 revision thread AQAUse the product rule, to find the differentiall of tan^2(4x) use the chain rule, and then you just change the tan4x's into y(Original post by 24DJF)
Anyone had a go at the January 2010, question 7b? I'm a bit stuck....

Or differentiating 3/x as 3ln(x). That happened on my C4 mock. I can't believe I lost 6 marks because of that silly mistake.(Original post by 24DJF)
Oh, and make sure we all don't make stupid mistakes... Like not integrating in a substitution question...
Woops.

Re: AQA MPC3 31/05/12 revision thread AQAWhat have you got so far? Remember y=tan4x so once you have it in terms of tan4x you can replace it with y(Original post by 24DJF)
I tried that, but I can't get it in the form it asks for :/

Re: AQA MPC3 31/05/12 revision thread AQAi keep getting around 60/75.
any ways to improve my scores in 1 day? obviously the real exam result will be alot lower because of nerves and making alot more silly mistakes.
i can do all the basic stuff thats on the syllabus and questions that are similar every year, i just cant do the new stuff where they try and trick you.Last edited by ReTurd; 29-05-2012 at 19:55. -
