Homework Help: Integration of (cosecx)^3 without using integration by parts

  1. Dec 5, 2013 #1
    1. The problem statement, all variables and given/known data

    Can anyone help me integrating (cosecx)^3 without using integration by parts?

    2. Relevant equations

    3. 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] ??
