Method for U Sub Calculator

The substitution integral calculator generally uses two methods for the evaluation of integrals like antiderivatives and antiderivatives. These methods are:

  1. Transform limit
  2. Re-substitute method

These methods are explained with their corresponding examples.

Example: Consider we have a an integral function 52∫ (x+1)2dx.


Let u = x+1 , Therefore, dx = du

Method 1: Tranform Limits

Substitute x=2 and x=5 into u equation

u = 2+1 = 3 , u = 5+1 = 6


$$ \int_2^5 (x+1)^2 dx \;=\; \int_3^6 u^2 du $$ $$ =\; \left[ \frac{1}{3} u^3 \right]_3^6 $$ $$ =\; \left[ \frac{1}{3} (6)^3 - \frac{1}{3} (3)^3 \right] $$ $$ =\; 72-9 $$ $$ =\; 63 $$

Method 2: Re-substitute method

Drop te limit of integration

$$ \int (x+1)^2 dx \;=\; \int u^2 du $$ $$ =\; \left[ \frac{1}{3} u^3 \right] $$

Re-substitute the u-equation and evaluate with the orignal x limits

$$ =\; \left[ \frac{1}{3} (x+1)^3 \right]_2^5 $$ $$ =\; \left[ \frac{1}{3} (6)^3 - \frac{1}{3} (3)^3 \right] $$ $$ =\; 72-9 $$ $$ =\; 63 $$

Frequently Asked Question

When u-substitution can be used?

Image result for Benefits of U Substitution Calculator. U-Substitution is a technique we use when the integrand is a composite function. What's a composite function again? Well, the composition of functions is applying one function to the results of another.

Why does substitution work in integration?

Usually, the method of integration by substitution is extremely useful when we make a substitution for a function whose derivative is also present in the integrand. By doing so, the function simplifies and then the basic formulas of integration can be used to integrate the function.

What is u-substitution in calculus?

"Integration by Substitution" (also called "u-Substitution" or "The Reverse Chain Rule") is a method to find an integral, but only when it can be set up specially. The first and most vital step is to be able to write our integral in this form: Note that we have g(x) and its derivative g'(x).
