Chapter 13, Problem 29E(choose chapter or problem)
Theory and Examples
Let \(f(x, y)=x^{2}-x y+y^{2}-y\). Find The directions u and the values of \(D_{u} f(1,-1)\) for which
a. \(D_{u} f(1,-1)\) is largest
b. \(D_{u} f(1,-1)\) is smallest
c. \(D_{u} f(1,-1)=0\)
d. \(D_{u} f(1,-1)=4\)
e. \(D_{u} f(1,-1)=-3\)
Equation Transcription:
Text Transcription:
f(x,y)=x2-xy+y2-y
D_u f(1,-1)
D_u f(1,-1)= 0
D_u f(1,-1) = 4
D_u f(1,-1)= -3
