I will say that (cos(2x)) 2 means: First calculate 2x, then find cosine of that and finally square that result. Notice that it is still 2x, not 4x. 2 cos(2x). Then,. Z x. 2 sin(2x)dx = − x2. 2 cos(2x) +. Z xcos(2x)dx. We now need to solve. R xcos(2x)dx, again by parts. This time, we use u = x and dv = cos( ... May 14, 2018 ... This video works through the integral of (sinx cos2x). This type of integral is typically found in a Calculus 1 class. Putting u = 2 x ⇒ I = 1 2 sin 2 x + c Hence the integral of cos 2 x is 1 2 sin 2 x + c , where c is an integration constant. β={ 1,cos x,sin x,cos2x,sin2x}. and let S=\operatorname{span}β.
