Common Errors When Writing and Solving Equations
... 1. Students add to one side and subtract from the other side when solving addition and subtraction equations. Remind them that equations are like a balanced scale. If you add weight to one side of the scale (adding a constant) you must add weight to the other side. If you take weight away (subtracti ...

... 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 ...
