derivative of

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

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

Solution steps

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

Apply exponent rule:

\frac{1}{a} = a^{- 1}

= \frac{d}{d x} ((x^{2} - 1)^{- 1})

Apply the chain rule:

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

= - \frac{1}{( x ^{2} - 1 ) ^{2}} \frac{d}{d x} (x^{2} - 1)

\frac{d}{d x} (x^{2} - 1) = 2 x

= - \frac{1}{( x ^{2} - 1 ) ^{2}} \cdot 2 x

Simplify

- \frac{1}{( x ^{2} - 1 ) ^{2}} \cdot 2 x : - \frac{2 x}{( x ^{2} - 1 ) ^{2}}

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

\frac{d}{df} (f (1) + f (- 2))

y = lo g_{10} (sin^{2} (x))

sin^{54} (x) + tan^{37} (x)

\frac{sin ^{3} ( x )}{ln ( x ^{3} )}

\frac{sin ^{2} ( x )}{x}
