Integral of cos(1/x) Thread starter Emmanuel_Euler;Integral of cos^2x We can't just integrate cos^2(x) as it is, so we want to change it into another form, which we can easily do using trig identities Integral of cos^2(2x) Recall the double angle formula cos(2x) = cos^2(x) – sin^2(x) We also know the trig identity sin^2(x) cos^2(x) = 1, so combining these we get the equation cos(2xWhere the interchange of integrals is justi ed by Fubini's theorem for improper Riemann integrals
