(ln(x/4))^'

解答

(ln (\frac{x}{4}))^{^{'}}

\frac{1}{x}

求解步骤

(ln (\frac{x}{4}))^{'}

使用连锁律:

\frac{1}{\frac{x}{4}} (\frac{x}{4})^{'}

= \frac{1}{\frac{x}{4}} (\frac{x}{4})^{'}

(\frac{x}{4})^{'} = \frac{1}{4}

= \frac{1}{\frac{x}{4}} \cdot \frac{1}{4}

化简

\frac{1}{\frac{x}{4}} \cdot \frac{1}{4} : \frac{1}{x}

= \frac{1}{x}

\int 2 x (2 - x) d x

d er i v a t i v e 3^{2^{x^{2}}}

x \to 0 lim (\frac{sin ( x ^{7} )}{x})

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