$\frac{{(1 - x^{2})}^{- \frac{1}{2}} \sin ({(1 - x^{2})}^{\frac{1}{2}})}{\sqrt{1 - \cos^{2} ({(1 - x^{2})}^{\frac{1}{2}})}}$

Step 1

Apply pythagorean identity.

$\frac{{(1 - x^{2})}^{- \frac{1}{2}} \sin ({(1 - x^{2})}^{\frac{1}{2}})}{\sqrt{\sin^{2} ({(1 - x^{2})}^{\frac{1}{2}})}}$

Step 2

Move ${(1 - x^{2})}^{- \frac{1}{2}}$ to the denominator using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$\frac{\sin ({(1 - x^{2})}^{\frac{1}{2}})}{\sqrt{\sin^{2} ({(1 - x^{2})}^{\frac{1}{2}})} {(1 - x^{2})}^{\frac{1}{2}}}$

Step 3

Pull terms out from under the radical, assuming positive real numbers.

$\frac{\sin ({(1 - x^{2})}^{\frac{1}{2}})}{\sin ({(1 - x^{2})}^{\frac{1}{2}}) {(1 - x^{2})}^{\frac{1}{2}}}$

Step 4

Cancel the common factor.

$\frac{\sin ({(1 - x^{2})}^{\frac{1}{2}})}{\sin ({(1 - x^{2})}^{\frac{1}{2}}) {(1 - x^{2})}^{\frac{1}{2}}}$

Step 5

Rewrite the expression.

$\frac{1}{{(1 - x^{2})}^{\frac{1}{2}}}$
