Find the extrema of f subject to the stated constraints.
f(x,y) = x - y,
x^2 - y^2 = 2
First lets get the function all in terms of x.
Looking at the constraint:
y^2 = x^2 - 2
y = sqrt(x^2 - 2)
Plugging this into f(x,y) we get:
f(x,y) = x - y = x - sqrt(x^2 - 2)
In order to find extrema of a function we take it's ...
