Multivariable Calculus Lecture 4 Boundary Curves And Absolute Maxima Multivariable calculus: lecture 4: boundary curves and absolute maxima and minima find the absolute maxima and minima of the function f(x,y)=x^2 xy y^2 over. We'll return later to the question of how to tell if a critical point is a local maximum, local minimum or neither. for now, we'll just practice finding critical points. example 2.9.6. f(x, y) = x2 − 2xy 2y2 2x − 6y 12. find all critical points of f(x, y) = x2 − 2xy 2y2 2x − 6y 12. solution.

Math S21a Multivariable Calculus Lecture Math S21a Multivariable 1.3 limits consider a function y= f(x) from rn to rm (or possibly a subset of rn).let x0 = (x0 1;:::x 0 n) be a point in r n and let y0 = (y0 1;:::;y 0 m) be a point in r m.we say that y0 is the limit of fas xgoes to x0, written. Let’s take a look at an easier, well shorter anyway, problem with a different kind of boundary. example 2 find the absolute minimum and absolute maximum of f (x,y) = 2x2 −y2 6y f ( x, y) = 2 x 2 − y 2 6 y on the disk of radius 4, x2 y2 ≤ 16 x 2 y 2 ≤ 16. show solution. in both of these examples one of the absolute extrema.
