Exercises integration by substitution
Web6 Optional exercises 4 1 When to substitute There are two types of integration by substitution problem: (a)Integrals of the form Z b a f(g(x))g0(x)dx. In this case we’d like to substitute u= g(x) to simplify the integrand. (b)Integrals of the form Z b a f(x)dx, when f is some weird function whose antiderivative we don’t know.

I guess my question is if you integrated the u-substitution as an indefinite integral you would get (u^4)/4 + C but the C goes away when you've constricted it to a set of boundaries.

Taking t = 1 + x 2, we get d t = 2 x d x. The integral then becomes The integral on the right evaluates to ln t + C, which becomes ln ( 1 + x 2) + C. Therefore, the answer is Since 1 + x 2 > 0, we do not need to include the absolute value in the ln ( 1 + x 2) term.

WebThe purpose of u substitution is to wind up with ∫ f (u) du Where f (u) du is something you know how to integrate. And remember du is the derivative of whatever you called u, it is NOT just some notation.
