limit as x approaches 2 of (x^2+1)/x

解答

x \to 2 lim (\frac{x ^{2} + 1}{x})

\frac{5}{2}

十进制

2.5

求解步骤

x \to 2 lim (\frac{x ^{2} + 1}{x})

代入值

x = 2

= \frac{2 ^{2} + 1}{2}

化简

= \frac{5}{2}

\frac{d}{d x} (e^{4} + ln (8))

\int e^{3 x + 4} d x

x \to 2 - lim (- 2)

a re a y = x + 3, y = \frac{1}{2} x + 3

\frac{\partial}{\partial x} (5 x^{2} + 5 y^{2})
