Khan Academy: Calculus: Intro to Parametrizing a Surface With Two Parameters

Can an equation have an infinite number of solutions? Allow your class to discover the relationship between the input and output variables in a two-variable equation. Class members explore the concept through tables and graphs and...

Sal adds a few more steps to these problems as he solves algebraic equations with two steps, though he states that "there's more than one way to do it." Those who become confused by increasingly complicated algebra problems on a test...

Solving equations is as easy as 1-2-3. Using two examples, the video shows the order of the steps to use when solving a two-step equation. It uses a vertical approach to perform the inverse operations to isolate the variable. To finish,...

Why is it a two-column proof? A video introduces the class to the concept of a two-column proof and how to set one up. The segment of a playlist on basic geometry highlights the types of reasons that can be in a proof.

This video is an introduction to parametrizing a surface with two parameters.

Video continuing to show how to parameterize a torus using two parameters by writing the position vector valued functions. [16:32]

This video demonstrates how to evaluate an expression with two variables using substitution. [1:46]

Part 2 of a 3-part video series showing how to calculate the surface integral of a torus. Video continues to find the surface area of the torus by calculating a cross product. [10:29]

Sometimes you'll need to solve an equation with multiple variables on each side. This step-by-step tutorial will show you how to set your equation to 0, factor out the GCF, simplify, write your answers as a set, then plug and chug to...

Video using the information about unit normal vectors to represent the surface integral for finding flux through a surface in two dimensions in a different way. The video also uses partial derivatives and the second definition of the...
