Surface Area Of Revolution Of Parametric Equations X Axis Y Axis Solving area and surface area problems using parametric equations. based on section 12.1 in brigg's calculus. This calculus 2 video tutorial explains how to find the surface area of revolution of parametric curves about the x axis and about the y axis. it contains 2.
Area Of Parametric Curves Youtube Examples demonstrating how to find a parametric representation for various surfaces. finding the equation of the tangent plane to a surface that is represent. Surface area. to find the surface area of a parametrically defined surface, we proceed in a similar way as in the case as a surface defined by a function. instead of projecting down to the region in the xy plane, we project back to a region in the uv plane. We will sometimes need to write the parametric equations for a surface. there are really nothing more than the components of the parametric representation explicitly written down. x = x(u, v) y = y(u, v) z = z(u, v) example 1 determine the surface given by the parametric representation. →r(u, v) = u→i ucosv→j usinv→k. Within − 2 ≤ t ≤ 3. the graph of this curve appears in figure 10.2.1. it is a line segment starting at (− 1, − 10) and ending at (9, 5). figure 10.2.1: graph of the line segment described by the given parametric equations. we can eliminate the parameter by first solving equation 10.2.1 for t: x(t) = 2t 3. x − 3 = 2t.

Problem #1 – find the parametric equations for the surface f (x, y) = 9 – x 2 – y 2. one way to parameterize the surface is to take x and y as parameters and writing the parametric equation as x = x, y = y, and z = f (x, y) such that the parameterizations for this paraboloid is: x = x, y = y, z = f (x, y) = 9 − x 2 − y 2, (x, y) ∈ r 2. Surface area generated by a parametric curve. recall the problem of finding the surface area of a volume of revolution. in curve length and surface area, we derived a formula for finding the surface area of a volume generated by a function [latex]y=f\left(x\right)[ latex] from [latex]x=a[ latex] to [latex]x=b[ latex], revolved around the x axis:.
