\frac{d}{d x} (ln (\frac{x + 2}{x - 2}))

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

Solution steps

\frac{d}{d x} (ln (\frac{x + 2}{x - 2}))

Apply the chain rule:

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

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

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

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

Simplify

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

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

y = 6 x^{4} ln (x)

f (x) = 5 x, at x = 5

\int tan (5 x) sec^{2} (5 x) d x

x - 2, x, [0, 4]

[x + (x + sin^{2} (x))^{7}]^{5}
