Parameterized sphere surface

WebNotice here, only one parameter was necessary, namely t. In much the same way, we will describe a surface by a vector function r (u, v) = h x (u, v), y (u, v), z (u, v) i. Note in order to parameterize a surface, we need two parameters, u and v. As u and v vary over the domain D, r (u, v) traces out the surface as terminal points of the ... WebIn the videos before, Sal calculated the surface area. You can think of this as summing up the number of the tiny surface elements – which is the same as assigning each surface element a value of one and then summing up over all ones. In the current video, Sal assigns each surface element a different value, namely x^2, depending on the surface element's x …
