limit as x approaches 0 of sin^x(x)

解答

x \to 0 lim (sin^{x} (x))

不存在

求解步骤

x \to 0 lim (sin^{x} (x))

若

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

则极限不存在

x \to 0 + lim (sin^{x} (x)) = 1

x \to 0 - lim (sin^{x} (x)) =

不存在

= 不存在

\frac{d}{d x} (cos (x^{2} - 2 x))

d er i v a t i v e y = \frac{2}{e ^{x} + e ^{- x}}

\int z cos (z) d z

9 y^{^{''}} + 10 y = 0, y (π) = 1

\frac{d}{d x} (9 x^{\frac{7}{5}} - 5 x^{2} + 1 0^{4})
