WebDec 30, 2012 · If you are asked about derivatives, you should be taking Calculus- but then you should surely know that "f' (ln (1+ cos (x))" is just bad notation. You mean "if f (x)= ln (1+ cos (x)), what is f' (x)?" Now, do you know the chain rule? Clearly, you are expected to because it is needed here. You have f (u)= ln (u) with u= 1+ cos (x).
