WebLet us consider the parametric definition of a sphere: where theta and phi are two incrementing angles, that we will refer to as var t and var u and Rx, Ry and Rz are the independent radii (radiuses) in all three cartesian directions, which, in the case of a sphere, will be defined as one single radius var rad. WebA cone with a rectangle moving from the base to the apex to show the cross sections. The rectangle is diagonal to the cone's base, so it makes varying sizes of ellipses, from largest to smallest. When the rectangle crosses the base, it makes a shape with one curved side and one straight side. Created with Raphaël. dec 27 famous birthdays
