limit as x approaches 6+of (-5x)/(x+6)

解答

x \to 6 + lim (\frac{- 5 x}{x + 6})

- \frac{5}{2}

十进制

- 2.5

求解步骤

x \to 6 + lim (\frac{- 5 x}{x + 6})

代入值

x = 6

= \frac{- 5 \cdot 6}{6 + 6}

化简

\frac{- 5 \cdot 6}{6 + 6} : - \frac{5}{2}

= - \frac{5}{2}

\int (sin (2 x) cos (2 x)) d x

\frac{d}{d x} (e^{x^{3} y})

\frac{\partial}{\partial y} (\frac{x + y}{x - y})

\int_{1}^{3} \frac{( 3 x ^{2} - 7 )}{x ^{3}} d x

f (x) = x^{3} e^{4 x}
