临界点与极值计算器
逐步求解临界点和极值
该计算器将尝试求出一元函数的临界（驻）点、相对（局部）极大值与极小值，以及绝对（全局）极大值与极小值。可以指定区间。
Your input: find the local and global minima and maxima of $$$f=x^{3} - 3 x^{2}$$$
Critical Points
$$$\left(x, f \left(x \right)\right)=\left(0,0\right)$$$
$$$\left(x, f \left(x \right)\right)=\left(2,-4\right)$$$
Global (Absolute) Minima
No global minima.
Global (Absolute) Maxima
No global maxima.
Local Minima
$$$\left(x, f \left(x \right)\right)=\left(2,-4\right)$$$
Local Maxima
$$$\left(x, f \left(x \right)\right)=\left(0,0\right)$$$
