... z = −1 − 2 3(x − π/3) − 3y. (2) Find all points on the surface z = x2 − 2xy − y 2 − 8x + 4y, where the tangent plane is horizontal. Solution: The tanget plane being horizontal implies n =< −fx , −fy , 1 >=< 0, 0, 1 >. This means that fx = 0 and fy = 0. Creating these equations, fx = 2x − 2y − 8 = 0 ...

... where r = x2 −x1 is the relative position vector. These appear to be two coupled second order differential equations because the relative position depends upon x1 and x2 ). Coupled differential equations require some effort to solve. The problem can be simplified if we appreciate that no external fo ...
