Hi, is it possible to differentiate;

-(1/3)ln|secx|.exp(x).sinx??

do we go about doing this the same way as normal differentiation for example;

first differentiate ln|secx| only and so on......?

Use the product rule.

The product is

$\displaystyle -\frac{1}{3}\ln |\sec x| \cdot e^x \sin x$.

Then, to differentiate [Math]e^x \sin x[/tex] use the product rule again. - Apr 15th 2009, 03:03 PMJhevon
