We want to find the maximum and minimum values of f(x, y) = 10x2 + 11y on the disk D: x2 + y2 < 1.
dolphi86 [110]

If you're just focusing on the boundary, it's the circle x^2+y^2=1. Parameterize it by taking x=\cos t and y=\sin t, with 0\le t\le2\pi. Then f(x,y) reduces to a univariate function g(t):

f(x,y)=10x^2+11y\iff g(t)=f(\cos t,\sin t)=10\cos^2t+11\sin t

Then you can find any extrema on the boundary by checking the critical points of g.
