Just like how Differentiation is the slope of the tangent drawn at a point on the curve, Integration is the area covered by the curve or a graph in a plane. Integration can be used to find areas and volumes below any curve.
Example:Integrate the function: ∫x3dx
So according to the above formula,
For the above example let’s go backwards,
Differentiate the function: y = x4/4
-> y’= x3 ->this is the question in the previous example to integrate!
Hence differentiation and integration are reverse process to each other!
Example: Integrate the function ∫x-2dx
-> x-1/-1 + c -> -x-1 + c
