Why is it important to find the area under a curve?

Definite integrals and areas found under the curve are essential in physics, statistics, engineering, and other applied fields. Learning about areas under the curve also makes you appreciate what you’ve learned so far and makes you see how amazing integral calculus is.

What are the application of integrals?

In Mathematics integrals are used to find: Center of mass(Centroid) of an area having curved sides. The average value of a curve. The area between two curves. The area under a curve.

Is area between curves always positive?

Finally, unlike the area under a curve that we looked at in the previous chapter the area between two curves will always be positive.

What does area under the curve mean in physics?

The area under the curve is the magnitude of the displacement, which is equal to the distance traveled (only for constant acceleration).

What does the area under the curve represent physics?

What do you need to find area under the curve?

The area under a curve between two points can be found by doing a definite integral between the two points. To find the area under the curve y = f(x) between x = a and x = b, integrate y = f(x) between the limits of a and b. Areas under the x-axis will come out negative and areas above the x-axis will be positive.

How can integrals be used in real life?

Several physical applications of the definite integral are common in engineering and physics. Definite integrals can be used to determine the mass of an object if its density function is known. Definite integrals can also be used to calculate the force exerted on an object submerged in a liquid.

How do we use integration in real life?

In Physics, Integration is very much needed. For example, to calculate the Centre of Mass, Centre of Gravity and Mass Moment of Inertia of a sports utility vehicle. To calculate the velocity and trajectory of an object, predict the position of planets, and understand electromagnetism.
