limit as x approaches 3-of ([x]-x)/(3-x)

解答

x \to 3 - lim (\frac{[ x ] - x}{3 - x})

0

求解步骤

x \to 3 - lim (\frac{[ x ] - x}{3 - x})

化简

= x \to 3 - lim (0)

x \to a lim c = c

= 0

\int \frac{1}{4 + 9 x ^{2}} d x

\frac{d}{d x} ((x - \frac{1}{x})^{4})

x \to 5 lim (- x^{2} + 8 x - 5)

\frac{\partial}{\partial z} (3 y z^{2})

\int_{1}^{10} 5 x - 1 d x
