derivative of

\frac{1}{4 - x ^{2}}

\frac{2 x}{( 4 - x ^{2} ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{1}{4 - x ^{2}})

Apply exponent rule:

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

= \frac{d}{d x} ((4 - x^{2})^{- 1})

Apply the chain rule:

- \frac{1}{( 4 - x ^{2} ) ^{2}} \frac{d}{d x} (4 - x^{2})

= - \frac{1}{( 4 - x ^{2} ) ^{2}} \frac{d}{d x} (4 - x^{2})

\frac{d}{d x} (4 - x^{2}) = - 2 x

= - \frac{1}{( 4 - x ^{2} ) ^{2}} (- 2 x)

Simplify

- \frac{1}{( 4 - x ^{2} ) ^{2}} (- 2 x) : \frac{2 x}{( 4 - x ^{2} ) ^{2}}

= \frac{2 x}{( 4 - x ^{2} ) ^{2}}

\int (2 sin (t) cos (t)) d t

x \to 0 + lim (\frac{cos ( x )}{x})

n \to \infty lim (n! + n^{3})

y^{^{''}} = 4 y, y^{^{'}} (0) = 1, y (0) = 0

y^{^{''}} - 18 y^{^{'}} + 81 y = t^{- 2} e^{9 t}
