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

• trig -

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.

the sigma was the E

and that questions that I posted is word by word what the question actually says which now makes me think there must be a typo
