Mathematical term for the smallest value of a function in a neighborhood; contrast with 最小値 (global minimum).
この関数の極小値を求めなさい。
Find the local minimum of this function.
The graph has two local minima.
極大値 is the local maximum, the opposite of 極小値.
Compound of 極 (extreme) + 小 (small) + 値 (value), directly corresponding to the mathematical concept of a local minimum.
