An example of finding the surface area along a closed curve using line integrals.

Watch a video to explore indefinite integral as antiderivatives.

Learn about functions and x-intercepts.

Video determing whether the graph of a set of points is a function, which in this case it is not. Includes an overview of what a function is. Describes the vertical line test. [4:07]

An instructional video explaining the concept of function inverses. A linear function is given and a diagram is drawn to show the mapping of some elements of the domain to the corresponding elements in the range. The inverse of the...

Exponents are number 34897 to the power of 0! The short video explains what a power function is. It also demonstrates how to identify the n portion in a standard, fraction, and square root example.

Does the point continually move along the graph? Pupils drag a line across two functions to determine whether they are continuous or not. They answer questions about the properties of continuous and discontinuous functions. Using their...

Line integral over a closed path (part 1). This video shows how to visualize and use line integrals to find the surface area along a closed curved. Problem is solved by using three different line integrals.

Using line integrals to find the work done on a particle moving through a vector field.

A brief video correcting a notational mistake that was made in the previous video on how scalar multiplication affects the determinant. The formula in the previous video shows the entries being multiplied by the sub-matrices, when really...
