Integration formula topic wise. Integration Formulas List
integration formula calculus formula is a most using formula for calculus in mathematic Actually, Integration is the reverse process of Differentiation. Therefore, it is essential to know the formula as well as the differential to solve the questions of integration. Integration Formulas is the process with the help of which any type of integration related questions can be solved easily.
Calculus is the biggest topic of Maths in class 12th. It covers about 44% part of Mathematics which includes topics like Differential, Integration, Santana, Derivative Equation etc. Among these, the biggest topic is Integration, which is very interesting. It is impossible to study it or solve the question without Integration Formulas.
Here all the integration formulas from Basic to Advance are displayed which help the most in solving the questions.

What is Integration?
In general, integration is the inverse process of differentiation, also known as inverse differentiation. It is actually a process of working opposite to the differential function which is called integration.
Thus, finding the integral of a function f (x) means finding a function f (x) whose derivative is f (x). Some special facts regarding this are as follows.
f'(x).dx = f(x) + C
Integral: The function whose integral is to be found is called integral.
Integration: The method of finding the integral of a function is called Integration.
Integral: The function whose derivative is integral is called the integral of the integral.
