Integral Calculator computes an indefinite integral anti-derivative of a function with respect to a given variable using analytical integration. Thus cos2xdx cos2x 1 2 dx. In this video I show you why the integral of cosx2 has no closed form solution and how you can use the Maclaurin Series to express this integral as a sum.

It also allows to draw graphs of the function and its. We can prove this in the following two methods. Integral of cos2x sin2x.

The integral of cos square x is denoted by cos 2 x dx and its value is x2 sin 2x4 C. If we apply integration by parts to the rightmost.

Split up the integral. Next cosine squared times 1 is. 12 dx cos2x dx 12 x sin2x2 C.

This can be solved for cos2x. Use the trigonometric identity cos 2 x 1 2 1 cos 2 x to write. Integrate x x-1 integrate x sin x2 integrate x sqrt 1-sqrt x integrate x x13 from 0 to infinity integrate 1 cos x2.

Int cos2xsinx dx. So we need to convert the sine square x to 1 minus cosine squared x. Cos2x cos2x 1 2.

The easiest way to calculate this integral is to use a simple trick. The second integral is the perfect integral. Since sin x is an odd function we have sin x exp x 2 2 σ 2 d x 0.
