### What is Meant by Area Under the Curve?

In mathematics, the area under the curve for the given function f(x) having the limits x= a and x = b is given by the definite integral formula. In case, if the area between two bounding values lies above the x-axis, then it has a positive sign. If the area between two values lies below the x-axis, then the negative sign has to be taken. The formula to calculate the area under the curve is given by: $A = \int_{a}^{b}f(x)dx$
