Firstly, thanks for these great videos you put out. Secondly, I haven’t seen any textbook questions where trig comes up in series for AS, but that seems to be a recurring theme in the past papers. Should I do some extra dedicated practice for that? Where can I find questions like that? Thanks
I've searched a few places but have not, the only thing that I can think of is the pearson homework books, which I don't have access to. They might have something I guess
HI sir, Thank you for these videos. For questions like the one at 03:58 (Q3b) when I put the matrix into my calculator and multiply I get long decimals that are equivalent to the surds instead of the actual surds. I use the SD button and it doesn't change anything and my calculator is on the MathO setting. I have the 991EX. Do you know how I can fix it or should I just do questions like this manually? thank you.
tan is defined as O/A where O is the Y coordinate and A is the x coordinate, to find gradient you do change in Y/Change in X so tanx = gradient (change in Y/Change in X)
