How do you use integration to find area under curve? Calculus Introduction to Integration Integration: the Area Problem 1 Answer Wataru Oct 17, 2014 The area #A# of the region under the graph of a function #f(x) ge 0# above the x-axis from #x=a# and #x=b# can be found by #A=int_a^bf(x) dx# I hope that this was helpful.
