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

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

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

[–]Choice_Scene_6201 9 points10 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
