No, it is not from a reference books, but from the exercise books. i didn't sure is it a further math because the cover of the books just write A-level math. and the question inside this books are VERY difficult.
i wonder if the integration/differentiation of inverse trigo function is in the A-level Math? because there are a lot of such questions in that books! (i check that inverse trigo is not in STPM math T either!) but thanks to Johnivan further math blog, i still able to solve that question.
yeah, i forgot to ask u that are u currently an a-level student?
