Thread: differentiating 3 functions

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
.

Then, to differentiate [Math]e^x \sin x[/tex] use the product rule again.

Thank you people I got it now.
