Integration can be used to calculate areas. In simple cases, the area is given by a single definite integral. But sometimes the integral gives a negative answer which is minus the area, and in more complicated cases the correct answer can be obtained only by splitting the area into several parts and adding or subtracting the appropriate integrals.

There are two ways to solve this problem: we can calculate the area between two functions and using the vertical elements and integrate with respect to x, or we can use the horizontal elements and calculate the area between the y -axis and the function integrating the functions with respect to y.
How do you find the total area between the curve #f(x)=cos x# and the x-axis on the interval #[0,2pi ]#? How do you find the area of the region that lies inside the curves #r= 1+cos(theta)# and #r= 1-cos(theta)#?

Calculus: Integrals, Area, and Volume. Notes, Examples, Formulas, and Practice Test (with solutions) Topics include definite integrals, area, “disc method”, volume of a solid from rotation, and more.
Definite Integration. Whenever we are calculating area in a given interval, we are using definite integration. Lets try to find the area under a function for a given interval. (1) Integrate. from [-2, 2]. Step 1: Set up the integral. Step 2: Find the Integral. *Note: We don’t have to add a “+C” at the end because it will cancel out finding.
