(\partial)/(\partial x)(ln(t))

解答

\frac{\partial}{\partial x} (ln (t))

0

求解步骤

\frac{\partial}{\partial x} (ln (t))

将

t

视为常数

常数微分:

\frac{d}{d x} (a) = 0

= 0

x \to + 2 lim (\frac{x - 7}{x + 3})

d er i v a t i v e \frac{2 x - 7}{5 x + 4} + x^{3}

\int \frac{8}{x ^{2} x ^{2} + 4} d x

\frac{d}{d x} (\frac{e ^{y}}{x + y})

\int (6 x^{2} cos (2 x^{3} + 1)) d x
