Sphere in the first octant
Webthe cone interesects the sphere on the above rightmost circle. Since everything symetric with respect all the axis and the origin, you can try to calcualte the volumet in the first octant and the multiply by 4 (as we're interested only in what happens above the x y − plane. WebThe spherical coordinates of P = (x ,y z) in the first quadrant are ρ = p x2+ y2+ z2, θ = arctan y x , and φ = arctan p x2+ y2 z . Spherical coordinates in R3 Example Use spherical coordinates to express region between the sphere x2+ y2+ z2= 1 and the cone z = p x2+ y2. Solution: (x = ρ sin(φ)cos(θ), y = ρ sin(φ)sin(θ), z = ρ cos(φ).) 2

Did you know?
Websphere x2 +y2 +z2 = a2 lying in the first octant (x,y,z,≥ 0). Solution. Once again, we begin by finding n and dS for the sphere. We take the outside of the sphere as the positive side, so n points radially outward from the origin; we see by inspection therefore that (8) n = xi +yj +zk a, where we have divided by a to make n a unit vector. WebApr 11, 2024 · mathmate The point (8,2,9) is in the first octant. The closest distance from the coordinate planes is the value y=2, which will therefore be the maximum radius of the required sphere. The standard equation of a sphere with radius r and centre (u,v,w) is given by (x-u)^2+ (y-v)^2+ (z-w)^2=r^2
WebOct 26, 2024 · Oct 26, 2024 at 12:59 1 As the region is in first octant, it would have been more clear to state that the region is bound between $z = 0$ and $z = \sqrt {x^2+y^2}$. If it is in first octant, it cannot be bound by $ ~ - \sqrt {x^2+y^2}$ though we can try and infer what is … WebA: Given, we need to evaluate the norm of the following vectors. i=<-1,2,4>ii=-i+7j.
