To convert this integral to integrals of the form displaystyle cos jx sin x dx rewrite sin 3x sin 2x sin x and make the substitution sin 2x 1 cos 2x Thus displaystyle begin align cos 2x sin 3x dx cos 2x 1 cos 2x sin x dx text Let u cos x text then du sin x dx 4pt Example 2 Evaluate the integral cos 2x ex dx cos 2 x e x d x Solution to Example 2 Substitution Let u cos 2x u cos 2 x and dv dx ex d v d x e x which gives u 2sin 2x u 2 sin 2 x and v ex dx ex v e x d x e x Apply the integration by parts cos 2x ex dx cos 2x ex 2 sin 2x ex dx cos
Integration by parts is a process that finds the integral of a product of functions in terms of the integral of their derivative and antiderivative It is frequently used to transform the Alvin L Jan 12 2018 excos x dx ex 2 sin x cos x C Explanation Alternatively we can use a nice little technique called complexifying the integral We notice that cos x is just the same as the real part of eix by Euler s identity ei cos isin We can use this fact to rewrite the integral like so
