Definately an E4. Anything over 70% is an E4. I'm pretty sure the person who sets the band cut-offs each yr for 4u sets them quite low (usually in the 60%s). I think last yr's paper was fairly difficult though, cause I know a few guys who got E4s and they reckoned they got 71-75/120. But anyway, yes, 71% would be an E4.

Look at question 4a). It was worth a large number of marks and it was a complete joke. I almost laughed when I saw it.

It's the "mental method" - a hybrid of the substitution and equating the coefficients (when necessary)

Say you have

Sub in x=2 to . Get this number and write it on top of x-2

Sub x=-4 to , write on top of x+4

So in partial fractions:



If the question contains repeated linear factors, like this:

Sub in x=2 to . Get this number and write it on top of (x-2)2

Sub x=-4 to , write on top of x+4

Now for the number on top of (x-2) I equate the coefficients of x2



So in partial fractions:





Sometimes I use this, but usually the above.




funny that you mentioned that, I thought the exact same thing

how does this let you find a,b,c where (ax+b)/(x-2)^2 + c/(x+4)? Also i dont see how you equated the coeff's of x^2 to get C+1/36=0,

I usually use the standard "supa cool method" or do it simultaneously after equating coeffs the normal way, but this way seems like it would save me valuable time. Please explain.

I can't believe I've cracked 3 digits =D. I could actually do the induction, I'm usually shit at that.

I got so confused with signs... I guess i should write neatly with signs XD

Anyway, i managed to get 108. Forgot how to find the area of an annulus and got confused with resolving forces ><"
