Evaluate the integral

The Correct Answer and Explanation is: 1. ∫sin⁡5(2t)cos⁡2(2t) dt\int \sin^5(2t) \cos^2(2t)\, dt∫sin5(2t)cos2(2t)dt Solution: Use substitution:Let u=sin⁡(2t)⇒du=2cos⁡(2t) dt⇒du2=cos⁡(2t) dtu = \sin(2t) \Rightarrow du = 2\cos(2t)\, dt \Rightarrow \frac{du}{2} = \cos(2t)\, dtu=sin(2t)⇒du=2cos(2t)dt⇒2du​=cos(2t)dt We write: sin⁡5(2t)cos⁡2(2t) dt=u5cos⁡(2t)⋅cos⁡(2t) dt=u5cos⁡2(2t) dt\sin^5(2t)\cos^2(2t)\, dt = u^5\cos(2t)\cdot \cos(2t)\, dt = u^5 \cos^2(2t)\, dtsin5(2t)cos2(2t)dt=u5cos(2t)⋅cos(2t)dt=u5cos2(2t)dt But we still have another cos⁡(2t)\cos(2t)cos(2t), so instead: write: sin⁡5(2t)cos⁡2(2t)=(sin⁡4(2t)sin⁡(2t))cos⁡2(2t)⇒(sin⁡4(2t)cos⁡2(2t))sin⁡(2t)\sin^5(2t)\cos^2(2t) = (\sin^4(2t)\sin(2t))\cos^2(2t) \Rightarrow (\sin^4(2t)\cos^2(2t))\sin(2t)sin5(2t)cos2(2t)=(sin4(2t)sin(2t))cos2(2t)⇒(sin4(2t)cos2(2t))sin(2t) Use identity sin⁡2(2t)=1−cos⁡2(2t)\sin^2(2t)
