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。

Enter a function of one variable:
Enter an interval:
Required only for trigonometric functions. For example, `(-2pi, 3pi)` or `[pi/2, oo)`. If you need `oo`, type inf.

If the calculator did not compute something or you have identified an error, or you have a suggestion/feedback, please contact us.

Your input: find the local and global minima and maxima of $$$f=x^{2} - 2 x + 3$$$

Critical Points

$$$\left(x, f \left(x \right)\right)=\left(1,2\right)$$$

Global (Absolute) Minima

$$$\left(x, f \left(x \right)\right)=\left(1,2\right)$$$

Global (Absolute) Maxima

No global maxima.

Local Minima

$$$\left(x, f \left(x \right)\right)=\left(1,2\right)$$$

Local Maxima

No local maxima.
