STEP II 2011 Discussion Thread

Really grasping at straws but do you think I could have just got a 2?

I completed q1 fully and from the discussion my answer seems to have no errors I am aware of. Then completed the whole of the first part of 2 but could only find 1 solution instead of 2 to the second half. Then did question 3 up until c where I managed to show it was increasing but not the inequality. I tried IBP on 6 with but this lead nowhere as I used the wrong u and v so I doubt I'll get any for this and then the very very first part of 4.

I think this is probably a 3 but it's so annoying as I did so much prep for it but just couldn't get started on a lot of the pure. I've never needed to do mechanics before after getting 4/5 pure so didn't think of even looking. Kicking myself in hindsight

Sounds on the better side of similar to what I did, and people have even said that it might be enough for a 1. Definitely should be a 2 I think, though.

These are the complete solutions to Q1,Q2,Q6

What do you think the chances are of a 2 in STEP II being accepted instead of a 1 in STEP I?

What uni?

Engineering at Cambridge

Your solution to Q6 has a fair few mistakes in it.

When you were asked to verify the integral in the case f(x)=tanx, you're not supposed to take n=1 and show it holds. You're supposed to show that it holds for all n.

Also, your part (ii) is completely wrong other than the derivatives you found at the start. It is the case of the original integral with f(x)=secx+tanx and n=4, rather than n=6 as you've seemed to take it. (see back to my solution on page 2 if you don't see what you're missing).

I haven't checked the others yet.

Solution to Q3...i think others have reached the same solution....
