Reduction Formula for Trigonometric Functions
- \int sin^{n}(x)dx=\frac{-Sin^{n-1}(x)Cos(x)}{n}+\frac{n-1}{n}Sin^{n-2}(x)dx.
- \int tan^{n}(x)dx=\frac{-tan^{n-1}(x)}{n-1}-\int tan^{n-2}(x)dx.
- \int sin^{n}(x)\: cos^{m}(x)dx=\frac{sin^{n+1}(x)cos^{m-1}(x)}{n+m}+\frac{m-1}{n+m}\: \int sin^{n}(x)\: cos^{m-2}(x)dx.
How can I learn integration fast?
The best way to learn integration is to first study and then practice. Find a good calculus textbook, such as Thomas’ Calculus, and first understand the conceptual ideas behind the integral and its relation to the derivative.
What is the reduction formula of Cos NX?
To derive the reduction formula, rewrite cosnx as cosxcosn−1x and then integrate by parts. But this gives you (n−1)∫cosnxdx somewhere on the right: In=sinxcosn−1x+(n−1)In−2−(n−1)In .

How many reduction formulas are there?
The reduction formulas have been presented below as a set of four formulas. Reduction Formula for basic exponential expressions. Reduction Formula for logarithmic expressions. Reduction Formula for trigonometric functions.
What is a reduction formula chegg?
Reduction formulas are the formulas used to reduce the quantities, such as powers, percent, logarithms, and so. Reduction formulas are nothing but reducing an integral to another integral involving some variables such as x, n, t, and so on.
What is the use of reduction formula?
Reduction formula is regarded as a method of integration. Integration by reduction formula helps to solve the powers of elementary functions, polynomials of arbitrary degree, products of transcendental functions and the functions that cannot be integrated easily, thus, easing the process of integration and its problems.
What is the importance of integration by reduction?
Integration by reduction formula helps to solve the powers of elementary functions, polynomials of arbitrary degree, products of transcendental functions and the functions that cannot be integrated easily, thus, easing the process of integration and its problems.
What is the reduction formula for cosine?
The reduction formula can be applied to different functions including trigonometric functions like sin, cos, tan, etc., exponential functions, logarithmic functions, etc. Here, the formula for reduction is divided into 4 types: ∫x n e mx dx = [ (1/m) x n e mx ]− [ (n/m) ∫x n−1 e mx ]dx
What is the reduction formula for exponential functions?
Reduction Formula for Exponential Functions 1 ∫x n e mx dx = [ (1/m) x n e mx ]− [ (n/m) ∫x n−1 e mx ]dx 2 ∫e mx /x n dx = − [e mx / (n−1)x n−1 ]+ [ (m/n−1) ∫e mx /x n−1 ]dx, n≠1 More
