derivative ln(y)

解答

导数

ln (y)

\frac{1}{y}

求解步骤

\frac{d}{d y} (ln (y))

使用常见微分定则:

\frac{d}{d y} (ln (y)) = \frac{1}{y}

= \frac{1}{y}

d er i v a t i v e y = x^{2} sin^{7} (x) + x cos^{- 6} (x)

\int \frac{1}{- 20 x - 20 x} d x

x y^{^{'}} + (1 + 2 x^{2}) y = x^{3} e^{- x^{2}}

\frac{d}{d x} (sec (7 x))

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