what is integration and differentiation
Integration is one of the two main operations of calculus, with its inverse, differentiation, being the other. Given a function f of a real variable x and an interval [a, b] of the real line, the definite integral.
DIFFERENTIATION: It is the procedure of finding derivatives. Derivative of a function is the slope of a curve at any given point. INTEGRATION: It is the reverse of differentiation and it calculates the area under the curve. See the picture for clarification:
