Hey, I remember you from the S2 thread - hope it went well for you!

I quite like FP2, with the exception of series and integrals . How are you feeling about it?

It's alright yeah. Same as you really okay with everything apart from series and integrals...

I like everything apart from iteration which is just silly.

FP3 was meant to secure the A* for me, one more above 90 (M2 and M3 already above 90), after that FP2 needs to be like 100 or I am screwed.

It was the too damn high grade boundaries meme for M3 I showed last time

Really am concerned with M3 now...I'm more uncertain with M3 than D2

M2 and 3 boundaries are silly but I think I got 100 in M3 unless I made a silly mistake I didnt see and would have got 100 in M2 but I misread the mass of a particle so lets say like 70/72, I think I should already be ok but if I have mucked up in either then I am screwed so I need FP2 to be like 100%.

Really cba to do FP2 lol. I feel bad for not practicing but the content becomes incredibly repetitive. Wondering how can I take shortcuts on this

To be fair, FP2 is the most STEP like A level exam we do in terms of topics.

Hey guys, is this a valid way of expanding ln(x) using Taylors series?

 ln(n) = ln(1+(n-1)) = n-1 - \dfrac{(n-1)^2}{2} + \dfrac{(n-1)^3}{3} - ... + (-1)^{r+1}\dfrac{(n-1)^r}{r} + ...

Hang on a second.... I think I've just had an idea while writing this. I don't think you can because...

 ln(x) \Rightarrow x \neq 0

so I guess my statement above is incorrect :ashamed2:

I assume you mean 9) (iv)??

Basically  \delta_{n+1} \approx g'(\alpha) \delta_n is just another iteration formula. So you can use iteration to find a value of n for  \delta_n < 10^{-6} \delta_1

Don't worry, Taylor series isn't on the spec for FP2, though I would help if I could.

Is anyone here sitting S3? If memory serves, just over 300 people a year sit it.
