what is meant by integration and differentiation
Suppose you need to find the slope of the tangent line to a graph at point P. The slope can be approximated by drawing a line through the point P and finding the slope by a line that is known as secant line.A function f in x is said to be differentiable at the point x = a if the derivative f'(a) exists at every point in its domain. The differentiation formula is given by:
For a function to be differentiable at any point x=a in its domain, it must be continuous at that particular point but vice-versa is necessarily not always true. The domain of f’(x) is defined by the existence of its limits.
If y = f(x) is a function in x, then the derivative of f(x) is given as dy/dx . This is known as the derivative of y with respect to x.
Also, the derivative of a function f in x at x = a is given as:
Derivative of a function f(x) signifies the rate of change of the function f(x) with respect to x at a point a lying in its domain.
If the derivative of the function, f’, is known which is differentiable in its domain then we can find the function f. In integral calculus, we call f as the anti-derivative or primitive of the function f’. The method of calculating the anti-derivative is known as anti-differentiation or integration.
Integration Rules
The integration of a function f(x) is given by F(x) and it is represented by:
R.H.S. of the equation indicates integral of f(x) with respect to x
F(x) is called anti-derivative or primitive.
f(x) is called the integrand.
dx is called the integrating agent.
C is the constant of integration or arbitrary constant.
x is the variable of integration.
From the above discussion, it can be said that differentiation and integration are the reverse processes of each other. Both differentiation and integration are operations which are performed on functions.

Integration and Differentiation
Integration and differentiation are fundamental concepts in calculus that involve the manipulation of functions to find new functions or relationships between quantities.
Integration:
- Integration is the process of finding the integral of a function. It involves finding the area under a curve or the accumulation of quantities over a given interval.
- The result of integration is an antiderivative, which represents the original function up to a constant.
- The symbol used for integration is the integral sign (∫), and the process is also known as finding the primitive function of a given function.
- Integration is used in various fields such as physics, engineering, and economics to calculate quantities like displacement, velocity, and area.
Differentiation:
- Differentiation is the process of finding the derivative of a function. It involves calculating the rate of change or slope of a function at a given point.
- The derivative represents the instantaneous rate of change of a function at a specific point.
- The symbol used for differentiation is the derivative sign (d/dx or f'(x)), and the process is also known as finding the slope of a curve.
- Differentiation is used to solve problems involving optimization, finding maximum and minimum values, and determining the behavior of functions.
In conclusion, integration and differentiation are two sides of the same coin in calculus. Integration focuses on finding the area under a curve or accumulation of quantities, while differentiation deals with finding the rate of change or slope of a function. Both concepts are essential tools for analyzing functions and solving a wide range of mathematical and real-world problems.
