# NCERT Solutions Class 12 Maths Chapter 7 Integrals

NCERT Solutions for Class 12 Maths Chapter 7 Integrals is an introduction to the other side of differentiation that is ‘Integration’. Differentiation gives us the rate of change or in terms of geometry the slope of the tangent at any given point in the curve however, it is by using Integration that we get to know the area under the curve. Integrals are inverse of differentiation, so if we differentiate a function, then the integration of the resultant gives us back the original function. NCERT solutions Class 12 maths Chapter 7 exposes the meaning and implementation of integration and provides different ways of calculating it.

Class 12 Maths Chapter 7 Integrals helps kids understand Integration, its type that is indefinite and definite integral, its relation with differentiation and the different ways integration can be done. Integration is a practical tool that is used to solve scientific and engineering problems. It helps to solve various questions from economics, finance, as well as probability.

## List of Formulas in NCERT Solutions Class 12 Maths Chapter 7

NCERT solutions Class 12 maths Chapter 7 covers lots of important concepts crucial for understanding higher grade maths. Students must make it a point to understand the derivation of the rules and formulas included. This will help them in applying the steps required for integration problems and reduce the scope of making mistakes. Kids are also advised to keep a formula chart enabling them to revise the formulas quickly and efficiently before examinations. Some important formulas covered in NCERT Solutions for Class 12 maths Chapter 7 are given below:

- ∫ f(x) dx = F(x) + C
- Power Rule: ∫ x
^{n}dx = (x^{n+1})/ (n+1)+ C. (Where n ≠ -1) - Exponential Rules: ∫ e
^{x}dx = e^{x}+ C

∫ a^{x} dx = a^{x} /ln(a) + C

∫ ln(x) dx = x ln(x) -x + C

- Constant Multiplication Rule: ∫ a dx = ax + C, where a is the constant.
- Reciprocal Rule: ∫ (1/x) dx = ln(x)+ C
- Sum and Difference Rules:

∫ [f(x) + g(x)] dx = ∫f(x) dx + ∫g(x) dx

∫ [f(x) - g(x)] dx = ∫f(x) dx - ∫g(x) dx

- ∫k f(x) dx = k ∫f(x) dx, , where k is any real number.
- Integration by parts: ∫ f(x) g(x) dx = f(x) ∫ g(x) dx - ∫[d/dx f(x) * ∫ g(x) dx]dx
- ∫cos x dx = sin x + C
- ∫ sin x dx = -cos x + C
- ∫ sec
^{2}x dx = tan x + C - ∫ cosec
^{2}x dx = -cot x + C - ∫ sec x tan x dx = sec x + C
- ∫ cosec x cot x dx = - cosec x + C
