quality work in a document. 1. Find the equation of the tangent plane at (2,3,1) to the surface x2 + y2 – xyz = 7. Do this 2 ways: a) Viewing the surface as the level set of a function of 3 variables g(x, y, z). b) Viewing the surface as the graph of a function of 2 variables f(x,y). 3. Consider the function f(x,y) […]
