Please briefly explain the solution and all steps, including substitution steps, triangles, and formulas used. Thank you!

-2 x e sin (2 x) du Put 21 = u 7 2 dx = du + du = du 2 - 2X e sim (2x ) dx = fe simu du 2 = Ife sinu du Set I - I e sinu du 2 We will solve it using integration by parts Recall that fig' = fg - ff'g ] Here f = sinu = COJu 1 9 = - e = u They 2 J = Ife sinu du = 1 2 - e sing - cosu ( - e ) du - 2 1 - e simu + fe coju du [ Again usury f fg' = Pg - sfig with fo cost, 19 = - 24 - u g = eIntegrate. Show all steps. Fully simplify. sin (2x) dx
