integrate xe^(x^2+1)

Original post by SOREN_TORETTO

integrate xe^(x^2+1)

Two ways of doing this - by reverse chain rule (inspection) or by substitution of x^2 + 1.

Inspection should be easiest.

Pull 1/2 outside the integral and do by inspection.

Is 8 past papers sufficient practice for C4 exam?

I plan on doing Jan 12, June 12, Jan 13, June 13, June 13(R), June 14, June 14(R), Jan 15 IAL.

An A grade on this exam makes or breaks my uni offer :frown:

Just do all the past papers from 2008 onwards. That's what I'm going to do, the day before the exam.

Can anyone explain why the integral of 1/(3-x) is -ln(3-x) whilst the integral of 12/(3-x) is -12ln(x-3) ???
Like why does what's inside the bracket change?

I was told that you need to achieve 480 ums for an A and 90% in c3/c4 + an A at AS to achieve an A*

You don't need an A at as, you need an A (480/600 UMS) overall.

So someone could average 75 between C1, C2, S1 and S2 but average 90 on C3 and C4 and still manage to get an A*? Amazing

I find Solomon papers degrading and demotivating as they're unnecessarily hard.
