Question

How to solve this integral
indefinite Integral of sin(x)/cos^2(x)
without using 'u' substitution?

Answer 1

hint:

\[\Large \frac{\sin(x)}{\cos^2(x)} = \frac{\sin(x)}{\cos(x)}*\frac{1}{\cos(x)}\]

Answer 2

\[\int\limits_{a}^{b}\frac{ \sin x }{ \cos ^2(x) }\]

Answer 3

Ah it makes sense now

Answer 4

I'm glad it does
