Integrationused to:
Find area under a curveFind volume of surfaces of revolution
Integrationused to:
Find area under a curveFind volume of surfaces of revolutionFind total distance traveled
Integrationused to:
Find area under a curveFind volume of surfaces of revolutionFind total distance traveledFind total change
Just to name a few
Area under a curvecan be approximated
without using calculus.
Then we’ll do itwith calculus
to find exact area.exact area.
