Hello,

I have no idea on how to solve the problem below. Do I take the intergral or do I set the given derivative equal to something?

Thanks!

Hint: $\displaystyle f'(x)=\frac{x^2-1}{1+\cos^2(x)}$

$\displaystyle \begin{gathered}

f'( - 1) = 0,\;f'( - 1^ - ) > 0,\;f'( - 1^ + ) < 0 \Rightarrow \quad \max \hfill \\

f'(1) = 0,\;f'(1^ - ) < 0,\;f'(1^ + ) > 0 \Rightarrow \quad \min \hfill \\

\end{gathered} $ - Jan 29th 2010, 08:46 AMdrumist
