臨界點與極值計算器
逐步求臨界點與極值
此計算器將嘗試尋找單變數函數的臨界（駐）點，以及相對（局部）與絕對（全域）的極大值和極小值。可指定區間。
Your input: find the local and global minima and maxima of $$$f=x e^{- x}$$$
Critical Points
$$$\left(x, f \left(x \right)\right)=\left(1,e^{-1}\right)\approx \left(1,0.367879441171442\right)$$$
Global (Absolute) Minima
No global minima.
Global (Absolute) Maxima
$$$\left(x, f \left(x \right)\right)=\left(1,e^{-1}\right)\approx \left(1,0.367879441171442\right)$$$
Local Minima
No local minima.
Local Maxima
$$$\left(x, f \left(x \right)\right)=\left(1,e^{-1}\right)\approx \left(1,0.367879441171442\right)$$$
