Evaluate using integration by parts, substitution, or both if necessary.
the intergral of cos 2x ln(sin 2x) dx
1/2 dw= cos2xdx
1/2 integrsl sign ln(w)dw
1/2 [(lnw)(w)- integral sign (1/w)(w) dw]
1/2 sin2xln(sin2x)-1/2 sin2x
This answer seems correct to me, but when I typed this in, the answer is said to be incorrect!
Please check my work and see if I made any mistakes.
