limit as x approaches 7 of x/(sqrt(x-3))

解答

x \to 7 lim (\frac{x}{x - 3})

\frac{7}{2}

十进制

3.5

求解步骤

x \to 7 lim (\frac{x}{x - 3})

代入值

x = 7

= \frac{7}{7 - 3}

化简

\frac{7}{7 - 3} : \frac{7}{2}

= \frac{7}{2}

x \to 3 lim (\frac{sin ( 5 x )}{x})

\frac{d y}{d x} + \frac{1}{3} y = \frac{1}{3} (1 - 2 x) y^{4}

x^{4} \frac{d y}{d x} - 2 x^{3} y = 4 x^{6} - 3 x^{2}

\int \frac{1}{x ^{2} - a ^{2}} d x

\frac{d}{d x} (2 cos (x) - 3 sin (x) + 4)
