Chapter 5: 2P (page 242)

Verify each of the following answers for an indefinite integral by one or more of the methods suggested above.
$2 . 鈭� \frac{d x}{\sqrt{x^{2} + a^{2}}} = \sin h^{- 1} \frac{x}{a}$ or $In (x + \sqrt{x^{2} + a^{2}})$ . Hint: To find the $\sin h^{- 1}$ form, make the substitution, $x = a \sin h u$ . or see Chapter, Sections $15$ and $17$ .}

Short Answer

Expert verified

It is proved that $鈭� \frac{d x}{\sqrt{x^{2} + a^{2}}} = \sin h^{- 1} \frac{x}{a} + C$

Step by step solution

01

The substitution method

Theu-substitution reserves the chain rule and it is used to solve integrals.

It is a method to obtain antiderivatives. Generally, formula for u-substitution is:

$鈭� f (g (x)) g' (x) d x = 鈭� f (u) d u$

Here, $u = g (x); d u = g' (x) d x$ .

02

Identify correct substitution

The given trigonometric integral is $鈭� \frac{d x}{\sqrt{x^{2} + a^{2}}}$ .

Substitution of $x = a \sin h u$ to obtain the solution in $\sin h^{- 1}$ form.

03

Applying substitution

Solve the integral by using the substitution of $x = a \sin h u$ .

$鈭� \frac{d x}{\sqrt{x^{2} + a^{2}}} = 鈭� \frac{a \cos h u d u}{a \sqrt{1 + \sin h^{2} u}} = 鈭� \frac{\cos h u}{\cos h u} d u$

04

Applying the identity

Now, apply the identity $\cos h^{2} x - \sin h^{2} x = 1$ :

$鈭� \frac{\cos h u}{\cos h u} d u = u + C = \sin h^{- 1} \frac{x}{a} + C$

Hence, on integrating $鈭� \frac{d x}{\sqrt{x^{2} + a^{2}}}$ the result is $\sin h^{- 1} \frac{x}{a} + C$
