\frac{d}{d z} (ln (\frac{a ^{2} - z ^{2}}{a ^{2} + z ^{2}}))

- \frac{2 a ^{2} z}{( z ^{2} + a ^{2} ) ( - z ^{2} + a ^{2} )}

Solution steps

\frac{d}{d z} (ln (\frac{a ^{2} - z ^{2}}{a ^{2} + z ^{2}}))

Apply the chain rule:

\frac{1}{\frac{a ^{2} - z ^{2}}{a ^{2} + z ^{2}}} \frac{d}{d z} (\frac{a ^{2} - z ^{2}}{a ^{2} + z ^{2}})

= \frac{1}{\frac{a ^{2} - z ^{2}}{a ^{2} + z ^{2}}} \frac{d}{d z} (\frac{a ^{2} - z ^{2}}{a ^{2} + z ^{2}})

\frac{d}{d z} (\frac{a ^{2} - z ^{2}}{a ^{2} + z ^{2}}) = - \frac{2 a ^{2} z}{- z ^{2} + a ^{2} ( z ^{2} + a ^{2} ) ^{\frac{3}{2}}}

= \frac{1}{\frac{a ^{2} - z ^{2}}{a ^{2} + z ^{2}}} (- \frac{2 a ^{2} z}{- z ^{2} + a ^{2} ( z ^{2} + a ^{2} ) ^{\frac{3}{2}}})

Simplify

\frac{1}{\frac{a ^{2} - z ^{2}}{a ^{2} + z ^{2}}} (- \frac{2 a ^{2} z}{- z ^{2} + a ^{2} ( z ^{2} + a ^{2} ) ^{\frac{3}{2}}}) : - \frac{2 a ^{2} z}{( z ^{2} + a ^{2} ) ( - z ^{2} + a ^{2} )}

= - \frac{2 a ^{2} z}{( z ^{2} + a ^{2} ) ( - z ^{2} + a ^{2} )}

\frac{d}{d x} (\frac{1}{3} π r (x) (x)^{2} h)

\int_{0}^{7} \frac{1}{9 + x ^{2}} d x

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

\int \frac{x ^{2}}{( x ^{2} + 6 )} d x

y = (4 x^{2} + 5) (5 x - 3)
