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] ??
