Title: Algebra Integrals Integration Notes
Description: This is notes for 2nd and 1st year students. Other can also buy if they want. Algebraic integration involves finding antiderivatives of functions and is an important concept in mathematics. This article explores algebraic integration techniques such as integration by substitution, integration by parts, partial fractions, and trigonometric substitution in depth. Integration by substitution involves changing the variable of integration by making a substitution of the form u = g(x). Integration by parts is used to find the antiderivative of the product of two functions, while partial fractions decompose a rational function into simpler fractions. Trigonometric substitution simplifies the integration of certain types of functions that involve trigonometric functions by using trigonometric identities. These techniques are useful for simplifying integrals and solving problems in various areas of mathematics.

Algebra Integrals Integration Notes
Introduction
Algebraic integration is an important concept in mathematics that involves finding
antiderivatives of functions
...
Integration by Substitution
Integration by substitution is a technique used to simplify an integral by changing the
variable of integration
...
The derivative of g(x) is then used to find dx in
terms of du, which is substituted into the integral
...
We can simplify this
integral by making the substitution u = x^2 + 1
...
Substituting this into the integral, we get:
∫ (x^2 + 1)^3 dx = ∫ u^3 (du/2x) = (1/2) ∫ u^3/x du
...
It is used to find the
antiderivative of the product of two functions
...
Suppose we want to integrate the product of two functions f(x) and g(x)
...
It is useful when one of
the functions has a simple derivative and the other function is difficult to integrate
...
A rational
function is a function of the form p(x)/q(x), where p(x) and q(x) are polynomials
...
For example, consider the rational function f(x) = (3x^2 + 2x + 1)/(x^3 + x^2 + x)
...
We can find these constants by equating
the numerators of f(x) and the partial fractions expression and solving the resulting system of
equations
...
The basic idea is to use trigonometric identities
to transform the integral into a form that can be easily integrated
...
We can simplify this
integral by making the substitution x = 2tanθ
