integral, from pi/4 to pi/3, of (ln(tan(x))/(sin(x)cos(x))dx

[Amandar]

\(\displaystyle \int_{pi/4}^{pi/3} \frac{ln(tanx)}{sinxcosx}dx\)


I dont even know where to start with this one. any suggestions? :?

If f(x) = ln(tan(x)), then what is f'(x)? :wink:

[Dr. Flim-Flam]

Let u = ln[tan(x)], then du = dx/sin(x)cos(x). Can you take it from here?

ahh makes sense. Yeh I'm sure I can thank you
