Integral Of Cosine 2x

Integral Of Cosine 2x. Integral of cos 2x cos x YouTube The key to solving any integral of this form is to use the cosine rule: cos (2x) = cos 2 (x) - sin 2 (x) = 2 cos2(x) - 1 = 1 - 2sin2(x) All of these forms are really helpful when solving problems such as this, and it's great if you can remmeber them, though if you get stuck in an exam, they can all be derived from the addition formulae that are probably on your fomula sheet! So, using the. Type in any integral to get the solution, steps and graph

Split the integral into two parts using the linearity of integration: ∫cos^2x dx = ∫ [ (1/2) + (1/2)cos (2x)] dx = (1/2)∫dx + (1/2)∫cos (2x) dx 3 The integral of cos 2x dx is (sin 2x)/2+C and the integration of cos^2x dx is (x/2)+(sin 2x)/4+C
