Hi,

$\displaystyle \int\frac{cosx-2xsinx}{cosx}dx=\int\frac{cosx}{cosx}dx - \int\frac{2xsinx}{cosx}dx$

How would one tackle the above problem? The numerator in the second term looks like an integration by parts but how is that handled with the denominator? A clue would be good for me to get started.

I have tried substitution but the x in the numerator gets in the way of du etc.

Thanks
