Homework Statement
Can anyone help me integrating (cosecx)^3 without using integration by parts?
Homework Equations
The Attempt at a Solution
i couldn't get a clue how to do it,i used fundamental identity but always ended up like
[∫(cosecx) dx] + [(∫(cotx)^2 . (cosecx) dx]
the left one will be simply reciprocal rule,but what about [(∫(cotx)^2 . (cosecx) dx] ??
