Substituting the boundaries directly accelerates the process since we do not have to substitute back to the original variables: Z b a g ( u ( x )) u 0 ( x ) dx Z u ( b ) u ( a ) g ( u ) du . You cannot directly integrate sin2(x). Use trigonometric identities and calculus substitution rules to solve the problem. Step 1. Use the half angle formula, sin 2(x) 1/2(1 - cos(2x)) and substitute into the integral so it becomes 1/2 times the integral of (1 - cos(2x)) dx. 1.integral sin (2x) / 4-cos (2x) dx , mis U 4-cos (2x) was asked by Shelly Notetaker on May 31 2017. 503 students have viewed the answer on StudySoup.
