limit as x approaches 0+of tan(2/x)

解答

x \to 0 + lim (tan (\frac{2}{x}))

发散

求解步骤

x \to 0 + lim (tan (\frac{2}{x}))

使用极限发散条件:

发散

= 发散

\int e^{x^{2} + 4 x + 3} (x + 2) d x

\frac{\partial}{\partial y} (\frac{x y}{( x - y )})

x \to 4 lim (\frac{x ^{2} - 5}{x + 5})

t an g e n t f (x) = 3 x^{2} - ln (x), (1, 3)

t an g e n t f (x) = x^{5}, at x = 4
