Parametrizing a cylinder
Web5 r = 1 is a cylinder, r = z is a doubleconeθ = 0 is a halfplaner = θ is a rolledsheet of paper 6 r = 2+sin(z) is an example of a surface of revolution. Spherical coordinates use the distance ρ to the origin as well as two angles θ and φ. The first angle θ is the polar angle in polar coordinates of the first two WebIf we restrict θ and z, we get parametric equations for a cylinder of radius 1. x = cosθ y = sinθ z = z 0 ≤ θ ≤ 2π, 0 ≤ z ≤ 4 gives a cylinder of radius 1 and height 4. More generally, x = rcosθ y = rsinθ z = z 0 ≤ θ ≤ 2π, 0 ≤ z ≤ h gives a cylinder of radius r and height h. If we want, we can change the names of the ...
Parametrizing a cylinder
Did you know?
WebFor example, if I am parametrizing a cylinder x^ 2 +y ^ 2=R to G(theta,z)=(Rcos(theta),Rsin(theta),z) does this mean that we are turning something in the theta-z plane into a three dimensional object ( a cylinder in this case ). Would this be considered a change of variable? To me this seems like a change in variable. Webmany others where we are intersecting a cylinder or sphere (or other “quadric” surface, a concept we’ll talk about Friday) with a plane. Step 1: Find an equation satisfied by the points of intersection in terms of two of the coordinates. We’ll eliminate the variable y. Note that the equation (P) implies y = 2−x, and substituting
