NettetThe given integral can be written as ∫ cos (x 2) (x dx). Let x 2 = u. Then 2x dx = du (or) x dx = (1/2) du. Substituting these values, the above integral becomes, ∫ cos u (1/2) du = (1/2) (sin u) + C (as the integration of cos x is sin x) = (1/2) (sin x 2) + C Answer: ∫ x cos (x 2) dx = (sin x 2 )/2+C
Nettet6. mar. 2024 · I = ∫ cos 2 θ = ∫ ( 1 − sin 2 θ) d θ. Further we can sin2x can be substituted as sin 2 x = 1 - cos2x/2. Then the above equation will become. I = θ − ∫ ( 1 − cos 2 θ 2) d θ. Integrating, I = θ – θ 2 + sin 2 θ 4. Moreover, I = θ 2 + sin 2 θ 4 + c. Hence the integration of cos^2θ is verified by using substitution method.
