Method used: In order to find the maximum and minimum values of a function f(x, y, z) that is subjected to the constraint
a) Find the values x, y, z and
b) Compute the values at the points from step a and find the maxomum and minimum values of f.
Calculation: It is given that the plane is
Let AB = Im, where A is an m×n matrix and B is an n×m matrix. If y ∼ MVN(μ,In) and BA is symmetric, find the distribution of yT BAy.
