WebA definite integral is the area under a curve between two fixed limits. The definite integral is represented as \(\int^b_af(x)dx\), where a is the lower limit and b is the upper limit, for a function f(x), defined with reference to the x-axis. To find the area under a curve between two limits, we divide the area into rectangles and sum them up.
