Performance Key

\times

wrong answer/cannot do the problem

s\ sec/ms/\mu s

performs correctly in time s

> s\ sec/ms/\mu s

does not finish in time s

>.<,s or >.<,\times

very difficult to convince system to do what you want (regardless of performance)

\frac{\cos(3x)}{\cos x} \rightarrow \cos^2 x - 3\sin^2 x

\frac{\cos(3x)}{\cos x} \rightarrow 2\cos(2x) - 1

A(x,y > 0); x^{1/n}y^{1/n} - (xy)^{1/n} \rightarrow 0

\log(\tan(\frac{1}{2}x + \frac{\pi}{4})) - \sinh^{-1}(\tan(x)) \rightarrow 0

\log\frac{2\sqrt{r} + 1}{\sqrt{4r + 4\sqrt{r} + 1}} \rightarrow 0
