Find the slope of tangent line to curve that is intersection to the surface z= (x^2) - (y^2) with plane x =2 , at point (2,1,3)
The ans given by the author is only∂z /∂y = -2
The Attempt at a Solution
Is my diagram correct ?
I'm wondering , why shouldnt we move the entire graph 'forward ' to x = 2 ? [/B]
