Describe the strategy you would use to integrate:

integral cot^m(x)*csc^n(x) dx .............if m and n are odd


work shown:

first you would express cot^m(x) in term of tan^m(x), secondly you would express csc^n(x) in terms of sin(x)

therefore cot^m(x)= 1/ tan^m(x)

therefore, csc^n(x)= 1/ sin^n(x)

therefore you would express 1/tan^m(x) in terms of sin^m(x) and cos^m(x).. which equals cos^m(x)/sin^m(x)

therefore integral of cot^m(x) csc^n(x) becomes integral of (cos^m(x)/sin^m(x)) *1/sin^n(x) dx

i don't know what to do with the rest... please help me with this question.. i'm stuck
