    is it correct? http://img245.imageshack.us/img245/4636/lagrange.th.jpg

    Extreme values (Lagrange multipliers)

    no, in fact g(x,y)=4x^2{}+9y^2{}=36 but well, I wrote it that way because is the way my book does

    you say so? I'm glad then... i thought it was wrong thanks you guys :)

    Extreme values (Lagrange multipliers)

    determine, if any, the maximum and minimum values of the scalar field f (x, y) = xy subject to the constraint 4x^2{}+9y^2{}=36 The attempt at a solution using Lagrange multipliers, we solve the equations \nablaf=\lambda\nablag ,which can be written as f_{x}=\lambdag_{x}...

    yeah i know... i realized too late :P i hope someone move this thread to that section look this is what i did http://img413.imageshack.us/img413/2806/volt.th.jpg

    Volume of a solid limited by two paraboloids

    Volume of a solid limited by these two paraboloids z=2x^2{}+y^2{} and z=12-x^2{}-2y^2{} hi can someone help me? I tried to solve this and my solution was \ 24\Pi is it correct? can someone solve this step by step?
