Homework Statement
Find equations of the tangent plant and the normal line to x-z=4arctan(yz) at (1+∏, 1, 1)
Homework Equations
The Attempt at a Solution
I took the partials and got fx=0 fy=0 fz=(-4y)/((yz)2+1) so for the plane i got -2z-2=0 and for the normal line I got .5z-2=0. I feel like I may have messed up somewhere, probably in taking the partials...
