tanx sin^2x capital sigma [0,2p]

That is neither an equation nor a question. What is capital sigma supposed to mean?
It usually means "sum of" in a mathematical series, but you have not written a series.
Is [0, 2p] supposed to be a domain [0, 2 pi] ?
Questions must be stated accurately to be understood.
