## 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:

- Transform limit
- Re-substitute method

These methods are explained with their corresponding examples.

**Example:** Consider we have a an integral function ^{5}_{2}∫ (x+1)^{2}dx.

Here,

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

So,

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

**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

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