@@TheNado i found it fine actually, didnt do the proof at the end and i remember skipping part a of the substitution (question 13 i think)and just doing part b. the semicircle question was challenging but i think i got the answer at the end. Aside from that everything else was allright tbh hbu?
this is my last video before I finish A-levels for good you carried me through these papers and I'm grateful for that, I hope this channel doesn't stay dead forever because it would be a shame
Hey, sorry to be a pain but I got a bit stuck at 45:09, how come you set the upper bound to 50.4? I thought that maybe since P(x=>50.4) you would put 50.4 as the lower bound as you're observing values beyond 50.4... These videos are insanely helpful btw thank you so much
