WebAug 13, 2014 · 1 Answer. We will use u -substitution, letting u = 4x. Thus, du = 4dx. Also, we will use the constant law of integration, namely ∫C ⋅ f (x)dx = C ⋅ ∫f (x)dx to rewrite the integral so that it contains du: We know that the integral of eudu will simply be eu. Remember the constant of integration: WebIf we straightly substitute in u = cos ( 2 x) We'd have d u = − 2 sin ( 2 x) d x Or equivalently − 1 2 d u = sin ( 2 x) d x When x = π / 2, then u = cos ( 2 π / 2) = cos ( π) = − 1 and when x = 0, u = cos ( 0) = 1. So we can transform the whole integral from ∫ 0 π / 2 sin ( 2 x) ⋅ f ′ ( cos ( 2 x)) d x to ∫ 1 − 1 − 1 2 ⋅ f ′ ( u) d u how many oscars does jeff bridges haveWebDec 15, 2016 · I'm designing a lesson for an Introduction to Integral Calculus class, and I want to encourage students to evaluate integrals without just going straight for the antiderivative and using the fundamental theorem of calculus.
