C3 Edexcel Maths 2018 Watch
I don’t understand when to use which differentiation method
integration is primarily C3 while all the integration rules come in C4
you have your product, chain and quotient rules
my query is to do with a seemingly easy part of trig but i just want to make sure cause dont want to lose silly marks
my teacher says that when you are answering questions that ask you to solve for x values between a range (i.e 0 < x <2π) you lose marks if you give anything out of the range whatsoever, but checking through some mark schemes they only withdraw accuracy marks if the extra values given are within the range so you would you still get marks if you extra correct values out of the range?
