Maths a level trigonometryWatch this thread
I wanna ask whether would be ask to prove any trigonometric identity( c3 ones particularly) in maths exam. I am doing edexcel maths.
I know the proof questions. What I meant is let's say if y=tanx Then dy/dx= sec^x I still know how to prove that but just wanna know would they test us on the main ones that are given in formula sheet or even if not. I hope you understand what I mean
