u-Substitution Recall the substitution rule from MATH 141 (see page 241 in the textbook). Theorem If u = g(x) is a differentiable function whose range is an interval I and f is continuous on I, then ˆ f(g(x))g′(x)dx = ˆ f(u)du. This method of integration is helpful in reversing the chain rule (Can you see why?) Let’s look at some ...
Answers - Calculus 1 Tutor - Worksheet 11 – Integration by Substitution 1. Evaluate the integral using substitution: ∫ t( t + y)5𝑑 Let = t + y and 𝑑 = t𝑑 . Then, 𝑑 =𝑑𝑢 2. Substitute these values into the integral: ∫ t( )5 𝑑 t =∫ 5𝑑 Integrate using the power rule: ∫ 5𝑑 = s x 6+𝐶
In each integral below, find the integer n that allows for an integration by sub-stitution. Then perform the integration. (there are two very natural choices for n). II. Integration by Parts: (Try to substitute u so that is simpler than u and so that v is no more complicated dx than dv.) Example. We have.
U-substitution is the first integration technique that should be considered before pursuing the implementation of a more advanced approach. This technique, which is analogous to the chain rule of differentiation, is useful whenever a function composition can be found within the integrated.
