limit as x approaches 0 of 2xln(x^2)

解答

x \to 0 lim (2 x ln (x^{2}))

发散

求解步骤

x \to 0 lim (2 x ln (x^{2}))

若

x \to a^{-} lim f (x) \neq = x \to a^{+} lim f (x)

则极限不存在

x \to 0 + lim (2 x ln (x^{2})) = 0

x \to 0 - lim (2 x ln (x^{2})) = 2 \cdot 0

不存在

= 发散

7 x y^{^{'}} - 2 y = - \frac{x ^{2}}{y ^{6}}

\int cos (t^{2}) d t

d er i v a t i v e x^{2} - 3 x - 5

\int 150 x + 7500 d x

t an g e n t f (x) = 7 x - 4 x, (1, 3)
