Nettet29. mar. 2024 · Given that, sin 2 ( a x) From the trigonometric formula cos 2 x = 1 − 2 sin 2 x, the value of sin 2 x is 1 − cos x 2. From this we are writing sin 2 a x as ⇒ sin 2 ( a x) = 1 − cos ( 2 a x) 2 Applying integration on both sides of the above equation, then we will get ∫ sin 2 ( a x) d x = ∫ 1 − cos ( 2 a x) 2 d x NettetAnother way to integrate once by parts to get I = ∫∞ 0bsinaxcosbx + acosaxsinbx x dx, then to use the formula 2sinαcosβ = sin(α + β) + sin( ∫ sinxyd = π 2sgn(y).
