limit as x approaches 2 of 2x^2-8

解答

x \to 2 lim (2 x^{2} - 8)

0

求解步骤

x \to 2 lim (2 x^{2} - 8)

代入值

x = 2

= 2 \cdot 2^{2} - 8

化简

2 \cdot 2^{2} - 8 : 0

= 0

d er i v a t i v e - \frac{4}{( 4 x - 17 ) ^{\frac{3}{2}}}

\int \frac{1}{y - x} d x

n = 1 \sum \infty \frac{1}{n ^{2} + 5 n}

x \to - 4 lim (x^{2} - 16)

\frac{d}{d x} (\frac{x ^{\frac{1}{2}}}{3 x})
