The area between two curves calculator is a free to use, virtually available online tool that gives the area occupied within any two curves. The area between two curves can be determined by computing the difference between the definite integrals of two functions (or in other words also known as integral with limits). 

In a two-dimensional geometry that is a 2-D plain, the area is nothing but a quantity that expresses the region occupied by the two-dimensional figure. 

Two functions are required to find the area, say f(x) and g(x), and the integral limits from a to b (b should be greater than a, read as ‘limit a tends to b’) of the function that represents the curve. 

The procedure to use the area between the two curves calculator is as follows:

Step 1: To start with, enter the smaller function, larger function and the limit value in the given input fields.

Step 2: Now you need to click the button “Calculate Area” to get the output.

Step 3: Finally, the area between the two curves will be displayed in the new window.

The area between the two curves is defined as the total region occupied between the two curves in a coordinate plane. The standard formula to calculate the area between two curves is as under:

If P : y = f(x) and Q : y = g(x) and x1 and x2 are the two limits, then the formula of Area Between Two Curves is: 

A=∫x2x1 [f(x)−g(x)]
