UTA Math 2326 Exam 2 Question and answers
UTA Math 2326 Exam 2 Question and answers What is the procedure for locating absolute maximum and minimum values on a closed bounded domain R? - Determine the values of the function at all critical points in R. Then find the maximum and minimum values on the boundary of R. The greatest of these values is the absolute maximum on R, and the least of these is the absolute minimum. How to numerically find the critical points of function f(x,y) - You take fx(x,y) and fy(x,y) and set them to 0 to find what x and y needs for that to work How to find if there is a local maximum, local minimum, or saddle point and what that point is. - Find D(x,y)=fxx(x,y)fyy(x,y) - (fxy(x,y))^2 at the critical point (a,b)
