Z=1 is that of a curve obtained when you intersect the above paraboloid by the plane z=1 Note that it is a circle perched atop the plane z=1 On the other hand, the single equation x² y² = 1 is the right circular cylinder of radius 1, whose axis is the zaxis It is clearly a surface and not a curveStack Exchange network consists of 178 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers Visit Stack Exchange
Sphere x^2+y^2+z^2=1
Sphere x^2+y^2+z^2=1-A sphere is the graph of an equation of the form x 2 y 2 z 2 = p 2 for some real number p The radius of the sphere is p (see the figure below) Ellipsoids are the graphs of equations of the form ax 2 by 2 cz 2 = p 2, where a, b, and c are all positive Find the maximum and minimum distance from the point 1, 2, 2 to the sphere x 2 y 2 z 2 = 36 Let (x, y, z) be any point on the sphere Its distance D from the point (1, 2, 2) is, D = x1 2 y2 2 z2 2 D 2 = f x, y, z = x1 2 y2 2 z2 2

Y z x Figure 1212 Distance in three dimensions In two dimensions, the distance formula immediately gives us the equation of a circle the circle of radius r and center at (h,k) consists of all points (x,y) at distance r from the intersection of this sphere with the yz plane; 1 Answer 0 votes The Sphere is x² y² z² = 1 And cone z = 6√ (x² y²) The volume of the Sphere is Where x,y and z are in Cartesian coordinates and Ѳ, φ and ρ are in Spherical coordinate system Where, x = ρ sin (φ)cos (Ѳ) y = ρ sin (φ)sin (Ѳ) z = ρ cos (φ) then consider z = 6√ (x² y²) φ = 946°X^2y^2z^24x2y6z10=0 becomes (x^2 4x) (y^2 2y) (z^2 6z) = 0 which becomes (x2)^2 (y1)^2 (z3)^2 = 4 1 9 which becomes
In this question Were you calling about the question of Austria with the center, you got your extra Y 00 and the radios you could you are Then the family will be X minus X They're all square That's why I minus squared zero square, let's see minus E zero square, equal to our square Now, in this question were given the question of the X squared plus y squared plus the square minus eight yIf f(x, y, z) = 0 and g(x, y, z) = 0 are the equations of two distinct spheres then (,,) (,,) = is also the equation of a sphere for arbitrary values of the parameters s and t The set of all spheres satisfying this equation is called a pencil of spheres determined by the original two spheres In this definition a sphere is allowed to be a subject to the constraint g(x, y, z) = 4, where g(x, y, z) = x 2 y 2 z 2 Using Lagrange multipliers the equations for critical points We rewrite the first three equations Now we multiply the constraint equation by (1 − λ) 2 to obtain Note that we
