yep thats what i got. I'm guessing you're doing fp2
Yeah, you?
2. (Original post by Qcomber)
If it does come up, they shouldn't have because knowledge of inverse trigonometrical integration is not on the spec for c3. Whereas the fp2 spec clearly states that you need to know that it even exists in the formula book.
They could probably lead you into it though giving you a substitution.

Yeah, you?
Yes, all other FPs too.

Same, I assume you're doing AQA?

Same, I assume you're doing AQA?
Yes. Hoping they won't destroy us like they did for my friends sitting M3

I would guess not, I have no idea what arcsin is

Its another way of writing sin^-1(x), or, 'inverse sin'.

Since that can be confused with (sinx)^-1, we have arcsin. Thats what i think/ been taught that it it, I could be wrong you never know

I prefer arcsin notation.
9. What would you say the best tips were for getting full marks? Always seem to slip up somewhere or another on a silly sign error or leaving answer in wrong form.
10. In the C3 and C4 exams, do they tell you which substitution to use in integration?

I would do every question twice if you have time. If you don't have time for every question then just be confident on your answers for the easy questions then check your answers for the ones you considered hard thoroughly.

On my C2 exam last year I literally did a question 3 times to make sure I was right, while finding a mistake the 2nd time around, the odds are, if you're aiming for full marks, that you're not going to make a mistake more than once.

Most of the time they will. If not it will be a 'Use a suitable substitution' question, where more often than not the substition will be inside the brackets.

For example x(7x+3)^(3/2)

I just made that up, but you would use the (7x+3) as a substitution.

When marking a past paper, write down on a seperate sheet all the mistakes you made. The notes should be detailed enough so it reminds you what you did wrong and how you could fix it. Do this for all the papers you do or have done, on the same sheets.

Every now and then look at that sheet and revise from it. Slowly you'll remember to look out for those small things and overtime, you should make less mistakes. It's worked for me so far.

I don't think I've seen one where they don't give you the sub, but C3 integrals the sub is very obvious.
15. If you have found the correct answer but you have used a method that is a bit different to the markscheme, would you lose marks?
16. anyone else aiming for an A*?

anyone else aiming for an A*?
Yep. Still a bit confused about how to get an A* overall though

Hopefully, yeah. Need an A* for the course I want to do

i am aswell. getting a B on the recent c4 that i just did didn't help.

nice.
