limit as x approaches 3 of tan((3pi)/4)

解答

x \to 3 lim (tan (\frac{3 π}{4}))

- 1

求解步骤

x \to 3 lim (tan (\frac{3 π}{4}))

x \to a lim c = c

= tan (\frac{3 π}{4})

化简

tan (\frac{3 π}{4}) : - 1

= - 1

\int \frac{1}{2 x + x} d x

\int r e^{\frac{r}{3}} d r

\frac{\partial}{\partial x} (x^{2} + y^{2} - y^{2} x - 2)

x \to \infty + lim (x^{3})

x \to 0 - lim (18 - \frac{4}{x ^{3}})
