Quick Review

What you’ll learn about Improper integrals Horizontally improper integrals (infinite limits of integration) Vertically improper integrals (intervals with points of infinite discontinuity) Comparison tests for convergence and divergence of improper integrals …and why The techniques of this section allow us to extend integration techniques to cases where the interval of integration [a,b] is not finite or where integrands are not continuous.
