It is very important that as this is not a definite integral, we must add the constant C at the end of the integration. Simplifying the above equation gives us a final answer: ∫sin 2 (X) dX = 1/2X - 1/4sin(2X) + C One way to convert sin's to cos's is to use sin^2(x) + cos^2(x) = 1 or cos^2(x) = 1 - sin^2(x) The sin's on the left are not squared. But from the factoring pattern I know I can get 1 - sin^2(x) in both denominators by multiplying each fraction by appropriate expressions (as you'll see shortly).
