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 $$$f=x \ln{\left(x \right)}$$$
Critical Points
$$$\left(x, f \left(x \right)\right)=\left(e^{-1},- \frac{1}{e}\right)\approx \left(0.367879441171442,-0.367879441171442\right)$$$
Global (Absolute) Minima
$$$\left(x, f \left(x \right)\right)=\left(e^{-1},- \frac{1}{e}\right)\approx \left(0.367879441171442,-0.367879441171442\right)$$$
Global (Absolute) Maxima
No global maxima.
Local Minima
$$$\left(x, f \left(x \right)\right)=\left(e^{-1},- \frac{1}{e}\right)\approx \left(0.367879441171442,-0.367879441171442\right)$$$
Local Maxima
No local maxima.
