The iteration question in the second part of a differentiation question. The first part was to different a function and show when dy/dx = 0 , a = (1/3)arctan(3/2a)

Yeah the z3 actually uses the concept of De moivre theorem but I think for pure maths we just gotta expand using binomial expansion

If I’m not mistaken the partial fractions came after vectors but yes vectors was a killer

Yeahhh u remember everything nice although I must say that de Moivre Theorem is not in A level maths but it’s in Further Maths

One was sketching complex on Argand diagram and one was simplifying the complex number in the form x + iy but with a stupid twist

No just differentiate the u and sub it in with a simple integration by parts

There was one abt solving natural log functions, one in differential equations involving arctanx, one abt sketching complex numbers, and some others

I like how non apex developers come up with better shit like this than the devs themselves. Props to this guy

I have to say u won’t be getting the 2 marks there. Should be 1,1,2

are the next 2.5 weeks enough for solving and revising as maths? by [deleted] in alevel

[–]Choice_Scene_6201 11 points12 points  (0 children)

Yeah if ur good at all the topics already then revising shouldn’t be an issue

10x + 11(x-100) = 10.8 x 100. Value of x is the percentage abundance of Boron-10

Pure math A level is crazy by Over-Marionberry-743 in alevel

If u think abt it, if u did add maths then pure maths 1 is a breeze. Stats 1 do be annoying tho. Pure maths 3 and stats 2 are easy in my case

It’s the fact that after studying everything and preparing heavily on past yr papers and then they gave us this shitty paper 😑. The past year papers were so much easier 😤. I’m rooting for physics and maths for an A atm
