An area between two curves can be calculated by integrating the difference of two curve expressions. The upper and lower limits of integration for the calculation of the area will be the intersection points of the two curves. The area is always the 'larger' function minus the 'smaller' function. Use the below-given Area Between Two Curves Calculator to find its area for the given two different expressions with the upper and lower limits respectively.
Area between two curves can be calculated based on the expression of a narrow rectangle that sits on one curve and goes up to another.
