Practice Problems: U-Substitution

1 :

Compute the indefinite integral of $f(x) = \sage {p1fdisp}$ : $\int \sage {p1fdisp}dx = \answer [validator=sameDerivative]{\sage {p1f1}}$

Don’t forget you can always factor out any constants that are multiplying the whole integrand, to make your life a little easier while you tackle the problem. Then look for functions inside other functions that have a derivative multiplying everything outside. In this case, try doing a substitution like $u = \sage {p1finside}$ and see if that helps. Don’t forget to calculate $du$ , and as always, don’t forget your friend the $+C$ !
