limit as x approaches 4 of (x^{q(x)}(4-x))/(e^{4-x)-1}

解答

x \to 4 lim (\frac{x ^{q (x)} ( 4 - x )}{e ^{4 - x} - 1})

未定义

求解步骤

x \to 4 lim (\frac{x ^{q (x)} ( 4 - x )}{e ^{4 - x} - 1})

如果

x \to a - lim f (x) = x \to a + lim f (x) = L

则

x \to a lim f (x) = L

x \to 4 - lim (\frac{x ^{q (x)} ( 4 - x )}{e ^{4 - x} - 1}) =

未定义

x \to 4 + lim (\frac{x ^{q (x)} ( 4 - x )}{e ^{4 - x} - 1}) =

未定义

= 未定义

x \to 9 lim (\frac{7}{x - 9})

\int x^{3} - 6 x d x

(x^{4} e^{- x})^{^{'}}

\frac{\partial}{\partial x} (4 x - 3 x^{4} y^{2})

\int \frac{t ^{5}}{t ^{2} + 2} d t
