Dont like inverse functions from inspection
I finally get "Proof by Mathematical Induction" the bit i didnt get was that when we assume for n = k that it comes out as eg
3 + 8 + 15 +....+ k(k+2) =
k(k^2 +2)/3 or what ever, then we do n = k+1 i.e.
3 + 8 + 15 +....+ k(k+2) + (k+1)((k+1)+2)
then we could sub
k(k^2 +2)/3 instead of the read then solve, i could see how we subed kinda thing, but i get it know;;; im a bit lazy for the next part, instead of making it into the exact first formula i just expand the formula and the k+1 bit + compare
Simple Harmonic motion is easy once you can understand the derivation of it, it took me several pages of doodleing and scribbling till i got to the formula, but i did it
Integration is the easiest ever!!! That stuff in my oppinion should be in 2U its so easy and then they could put 4U integration into 3U and put some more Uni core Integration into 4U. I also rekon that they should ditch conics in 4U and put Vectors from calculus or something more interesting
After doing some of the 3U i fell that Advanced Mathematics (2U) isnt advanced at all, infact, it should be called general!
Has every one done their tests yet, when is that, haven't you guys finished high school, what i mean is, will you guys be coming back next term?
