Make your first steps in evaluating definite integrals, armed with the Fundamental theorem of calculus.

Functions defined by definite integrals (accumulation functions) Finding derivative with fundamental theorem of calculus Finding derivative with fundamental theorem of calculus: …

An improper integral is divergent, where the output doesn't have a definitive value, when the value of the integral becomes ± infinity. On the other hand, if an improper integral is convergent, the …

Since definite integrals are the net area between a curve and the x-axis, we can sometimes use geometric area formulas to find definite integrals. See how it's done.

Performing u -substitution with definite integrals is very similar to how it's done with indefinite integrals, but with an added step: accounting for the limits of integration.

Improper integrals practice problems.Oops. Something went wrong. Please try again. Uh oh, it looks like we ran into an error. You need to refresh. If this problem ...

Sal evaluates definite integrals of functions given their graphs. He does so using various properties of integrals.

Finding definite integrals using algebraic properties Get 3 of 4 questions to level up!

In practice, I would use a calculator or Wolfram Alpha to solve one of these integrals. The hard part, which typically requires more human intelligence, is getting the double integral to the …

Improper integrals are definite integrals where one or both of the boundaries is at infinity, or where the integrand has a vertical asymptote in the interval of integration. As crazy as it may sound, …
