求反函数 d/d (\sqrt[3]{1/(4x^2)})

解答

求反函数

\frac{d}{d} (3 \frac{1}{4 x ^{2}})

\frac{x}{2 x ^{2}}, - \frac{x}{2 x ^{2}}

求解步骤

y = \frac{d}{d} 3 \frac{1}{4 x ^{2}}

用

y

替代

x

x = \frac{d}{d} 3 \frac{1}{4 y ^{2}}

求解

y, x = \frac{d}{d} 3 \frac{1}{4 y ^{2}}

\frac{x}{2 x ^{2}}, - \frac{x}{2 x ^{2}}

in v erse f (x) = y^{2} - 8 y

in v erse f (\frac{x + 2020}{x + 2022}) = x + 2021

in v erse \frac{y ^{2}}{y ^{3}}

in v erse e^{5 x + 2} + 4

in v erse f (x) = \frac{4}{7 + x}
