I actually got the problem solved and thank you for everything...I found a point inside the region that didn't satisfy the constraint, then I checked the top of the cone boundary and where g(x,y) =x^2+y^2, and again where z is [0,2] it all worked out great...thank you again for your efforts...

Ok.. ..my vertical z plane cannot exceed 2 because z^2 <= 4 and it cannot be lower than 0 where it hits the xy plane.. my x^2+y^2 is a circle in standard form that cannot exceed radius 2 or be smaller than radius 0.. so in my mind the constraint is a cylinder shape two units in height...

Ok I managed to get it...:D I will get my Latex game together for any future post and thanks CAF123 for the step by step instructions and for letting me know about Hessian... cheers guys..

Hey all...thanks for the info ...I checked my fy=0 using the complete the squares method and the quadratic formula and they both give me the same result.. :( ..the problem with the questions I'm doing is that he never taught us the Hessian in class...and its not even in our Stewarts...

oh thank you...I am new to this sort of thing...and I will follow up on that tutorial as soon as i can... ...the Fx mistake was actually a mistype on my part...the correct Fx is written here on my paper...sorry and thanks for that...I will be more aware in the future...

Good Day, My professor historically has put more advanced questions on the final exams than can be found in our textbook. My supplements and extensive search engine use have not allowed me to get any further...Ive hunted through as many examples as I could find but cannot seem to find a...

That was superb...thank you very much for your time and effort and being so lucid in your explanation...I was only unfamiliar with term nabal "look at points where \nabal f = 0 inside that sphere"... which I guess means I did not have that symbol in my computers font selection? ..your answer...

My first post and I am new to forum etiquette, please go easy on me. I have an exam in a few days and have a good grasp on the content. Historically the professor has been putting harder Lagrange questions on the exam than are available in my textbook and supplement books or that I can find...
