limit as x approaches 3 of cos(1/(x-3))

解答

x \to 3 lim (cos (\frac{1}{x - 3}))

发散

求解步骤

x \to 3 lim (cos (\frac{1}{x - 3}))

使用极限发散条件:

发散

= 发散

\frac{d}{d x} (e^{x^{2} + y^{2}})

\frac{d}{d x} (0.005 x^{2} - ln (x^{16}) + 70)

d er i v a t i v e y = \frac{6 x ^{2} + 8 x + 2}{x}

d er i v a t i v e - 4 x^{\frac{1}{2}}

s im pl i f y \frac{x}{2} ln (\frac{1 + x}{1 - x}) - 1
