Use this form to determine the center and radius of the circle. Match the values in this circle to those of the standard form. The variable r r represents the radius of the circle, h h represents the x-offset from the origin, and k k represents the y-offset from origin. The center of the circle is found at (h,k) (h, k).

2019年12月7日 · The ecuation of the paraboloid is $z=9-x^2-y^2$ I know that I can parameterize it in cartesian coordinates as $r(x,y)=(x,y,9-x^2-y^2)$ but I see in a book this parameterization of it that is $r(t)=...

2018年3月13日 · #y=9-x^2# attains greater values than #y=x+1#. therefore #y=9-x^2# is above #y=x+1# in the given interval. The area between these two functions in the given interval will be: #int_(-1)^(2) (9-x^2)-(x+1) dx#
