1. Introduction. We can obtain the area between a curve, the x-axis, and specific ordinates (that is, values of. x), by using integration. We know this from the units on Integration as Summation, and on Integration as the Reverse of Differentiation.
Integrals and Area Under the Curve | Desmos. Define your favorite function: f x = x2 − 1. Compute the integral from a to b: ∫b a f t dt. a = 0. b = 2. Visualize the area under the curve: f x> 0: 0, f x <0: f x <y < f x> 0: f x, f x <0: 0 a <x <b, b <x <a.
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.
