Question

When the areas cross over the lower bounding curve ( including X axis if that is the lower curve), what criteria is applicable to find the total area bounded by the curves.

Answer 1

Sometimes this happens that the curves bounding the region crosses each other(i.e intersect each other), in that case under one part lower bound curve becomes upper bound and upper bound curve becomes lower bound and in other part there is no change, in that case we have to break the integral in two parts, one from left bound to the intersection of curves and other from intersection to right bound.

If you have any further doubts regarding this please feel free to ask.
