limit as x approaches a of 3sqrt(x^2-6x)

解答

x \to a lim (3 x^{2} - 6 x)

3 a^{2} - 6 a

求解步骤

x \to a lim (3 x^{2} - 6 x)

代入值

x = a

= 3 a^{2} - 6 a

\frac{d}{d x} (x^{3} - x^{2} - 3 x + 10)

d er i v a t i v e y = arccot (x)

\int_{0}^{6} \frac{36}{x ^{2} + 36} d x

\frac{d}{d x} (\frac{2 ^{x}}{ln ( 2 )})
