Khan Academy: Add Vectors: Magnitude & Direction to Component

Add two vectors in magnitude and direction form to get a new vector in component form. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Add two vectors in magnitude and direction form to get a new vector also in magnitude and direction form.

An interactive java applet model allows students to explore vectors. Students can practice finding the direction and magnitude of a vector given its x and y-components as well as practice finding the x and y-components given a vector's...

Video showing that the standard basis is an example of an orthonormal basis. Explains how orthonormal bases make good coordinate systems since they make it easy to find coordinates. A general orthonormal basis is defined and then it is...

This video demonstrates how to set up an equation for direct variation and solve for the variable "k" which represents the constant of proportionality. [1:44]

Find a unit vector in the direction of a given vector. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

The second video on Benford's Law from the Khan Academy. This video connects Benford's Law to the logarithmic scale in an effort to explain why it holds true, particularly in data that grows exponentially. [6:27]

The final segment in the Khan Academy's series on function inverses. Similar to the previous video, this segment does another example for finding the inverse of a quadratic function. Again the instructor explains the need for restraints...

Add and subtract vectors given in component form. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Determine if two vectors shown on a graph are equivalent. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.
