Find $f^{(2012)}(\pi/6)$ if $f(x)=\sin x$
Here's the hint from the question paper: You may use Maclaurin series of $\sin x$ and $\cos x$; the formula $\sin(a+b) = \sin a \cos b + \cos a \sin b$ may be useful.
It is quite complicated to me. Btw this is my math graded homework. I know how to find derivative when $x = 0$, but i can't proceed with this qn coz of the $\pi/6$. Any ideas?
