limit as x approaches 3-of sqrt(9-x^2)

解答

x \to 3 - lim (9 - x^{2})

0

求解步骤

x \to 3 - lim (9 - x^{2})

代入值

x = 3

= 9 - 3^{2}

化简

= 0

t an g e n t f (x) = \frac{x + 2}{x ^{2} - 9}, at x = 1

\int 3 x - 12 d x

\frac{d}{d x} (\frac{3}{2 x} + \frac{4 x}{5})

d er i v a t i v e y = \frac{3 x + 4}{2 x - 1}

d er i v a t i v e f (x) = (x^{6} - 4 x^{2} + 2) ln (x)
