Consider the functions and (a) Show that both functions have a critical point at (b)
Chapter 13, Problem 60(choose chapter or problem)
Consider the functions.
\(f(x, y)=x^{2}-y^{2} \text { and } g(x, y)=x^{2}+y^{2}\)
(a) Show that both functions have a critical point at (0, 0).
(b) Explain how f and g behave differently at this critical point.
Text Transcription:
f(x,y)=x^2-y^2andg(x,y)=x^2+y^2
