I need some help with one of my tutorial questions. This is the question
http://img122.imageshack.us/img122/9820/ques3dd3.jpg
For Part (a), I have found the partial derivatives as
Fx (x,y) = Cos(x) Sin(y)
Fy (x,y) = Sin(x) Cos (y)
Then to find the stationary points, Let Fx = 0 and Fy = 0. But I am not sure how to find the values..
For Part (b), I have no idea how to solve it..
For Part (c), I know the chain rule for two variables but I am not sure how to apply it to this question. If someone could point out an example that would be great =)
Thx for the help!
