limit as x approaches-2 of x^5+8x-3x+7/9

解答

x \to - 2 lim (x^{5} + 8 x - 3 x + \frac{7}{9})

- \frac{371}{9}

十进制

- 41.22222 \dots

求解步骤

x \to - 2 lim (x^{5} + 8 x - 3 x + \frac{7}{9})

代入值

x = - 2

= (- 2)^{5} + 8 (- 2) - 3 (- 2) + \frac{7}{9}

化简

(- 2)^{5} + 8 (- 2) - 3 (- 2) + \frac{7}{9} : - \frac{371}{9}

= - \frac{371}{9}

x \to π lim (+ (\frac{x}{sin ( x )}))

x \to 1 + lim (x^{l n (l n (x))})

x \to 0 + lim (\frac{2}{sin ( x )})

x \to 0 lim (\frac{- sin ( x )}{x})

x \to 0 lim (\frac{b ^{x} - a ^{x}}{x})
