Parametric Calculus Surface Area Example 1 Sphere

Parametric Calculus Surface Area Example 1 Sphere In this video i go over an example using the surface area formula for parametric curves, and this time use it to determine the surface area of a sphere with radius r. 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.

Parametric Surface How To W Step By Step Examples We are much more likely to need to be able to write down the parametric equations of a surface than identify the surface from the parametric representation so let’s take a look at some examples of this. In this video i go over an example using the surface area formula for parametric curves, and this time use it to determine the surface area of a sphere with radius r. Finding surface area of any given surface, \ (s\), is straightforward now that we have found \ (ds\). we integrate \ (ds\) over the entire surface to find the total area. In this section, we are interested in finding the surface area when we are given the parametric representation of the surface. it is naturally we know that the formula has to come from riemann sum.

We've already seen how to compute tangent planes to level surfaces of a function using gradients. now we'll see how to easily compute tangent planes to parametric surfaces. We have discussed parameterizations of various surfaces, but two important types of surfaces need a separate discussion: spheres and graphs of two variable functions. In this video we apply what we have learned previously about surface area for a parametrically defined surface to the specific example of a sphere.
