Question

F(x,y,z) finding minimum question

F=ax^2+by^2+cz^2
a,b,c are constants
Where is the minimum of this equation

Answer 1

A "minimum" and a "maximum" are two extreme points of a function that represent the lowest or the highest value in a given interval or the domain.
You can find these points by derivating the function and looking for the value that makes f'(x)=0
