To integrate sin2x cos2x, also written as cos2x sin2x dx, sin squared x cos squared x, sin2(x) cos2(x), and (sin x)2 (cos x)2, we start by using standard trig identities to to change the form. sin x dx y sin2k1 x cosnx dx y sin2x k cosnx sin x dx sin2x. But the side of length C joins the points (cosy, siny) and (cos x, sinx) and so we also have, by Pythagorous Get the answer to Integral of sin(x)2 with the Cymath math problem solver - a free math equation solver and math solving app for calculus and algebra.int(sin(x)2,x). The integral becomes du/u. ln u C. ln (2 sin x) C. I hope that helps. Let me know if you need any clarifications on my answers. I will be happy to provide them.

Integrate[ (2sin2x-cosx) /(6-cos2x-4sinx)]dx. Babu Raje. Feb. Ok, I know that sin 2x can be substituted out for 2 sin x cos x. so now I have the Integral of ( sin x ) ( 2 sin x cos x ) dxwhen you get the integral of 2 sin2x cos x dx use u substitution. u sinx du cosxdx. This implies that sin2x 2sinxcosx. Now for finding the antiderivative sin2x we will use the substitution method. We will find sin2x dx 2sinxcosx dx. Jerry L. Kazdan. sinx. sin 2x .The key to obtaining this formula is either to use some imaginative trigonometric identities or else recall that eix cos x i sin x and then routinely sum a geometric series. I am trying to do the Integral of dx / (sinx cosx) 2 but I seem to be going round in circles, I tried a substitution but got nowhere, any ideas anybody? You can then calculate te integral of x cos(2x) using partial integration, or using this trick: The integral of sin(px) is -1/p cos(px). Then du -sinxdx and dx (du)/(-sinx).Sta. Does sin(pi-x) sin(x)? Tri.

No, "sin x2" MEANS sin(x2) and cannot be integrated in that way. If your function is really ( sin(x)if we do a maclaurin series expansion on sin(x2) cant we use that to find the integral of sin(x2)dx? Related QuestionsMore Answers Below.
