it felt easy enough tbh, yea the edexcel website says 70/75 for 90ums
its a method i miss a lot, hopefully once I do it properly in school itll be easy to spot. the other integral was nasty, i ended up subbing e^x = tanu and then changing everything back in terms of x at the end
its stil about 4 months until FP3 so im not too worried yet, just got to keep practicing
yea i feel the same, theyre still scary questions but its more a "wow this will a nice challenge" these days as opposed to a month or two ago when it was a "omg get this away from me"
