Consider the indefinite integral cos" (6t) sin(6t) dt. The most appropriate substitution to simplify this integral is u = Σ Then du = M dt, so sin(6t) dt = c du, where the constant c = Σ After making the substitution we obtain the integral f(u) du, where f(u) = Σ This last integral, when evaluated, is Σ After substituting back for u we obtain the following final form of the answer: cos" (6t) sin(6t) dt = Σ
