Chapter 5: Q. 89 (page 419)

Use the chain rule to prove the formula for integration by substitution:
$鈭� f' (u (x)) u' (x) d x = f (u (x)) + C .$

Short Answer

Expert verified

After using the chain rule for integration by substitution its is proved that $鈭� f' (u (x)) u' (x) d x = f (u (x)) + C .$

Step by step solution

Step 1. Given Information

Use the chain rule to prove the formula for integration by substitution:

$鈭� f' (u (x)) u' (x) d x = f (u (x)) + C .$

Step 2. To solve taking the left hand side integral.

$y = 鈭� f' (u (x)) u' (x) d x$

Let

$t = u (x) \frac{d t}{d x} = u' (x) d t = u' (x) d x$

Step 3. Now the integral after substitution.

$鈭� f' (u (x)) u' (x) d x = 鈭� f' (t) d t 鈭� f' (u (x)) u' (x) d x = f (t) + C$

Substituting the value of $t$ .

$鈭� f' (u (x)) u' (x) d x = f (u (x)) + C$
