Algebra 81 - Division with Complex Numbers
Dividing complex numbers can be more complicated than multiplying complex numbers since when the result is a fraction, in order to write that fraction as a complex number in standard form, it must be separated into a real part plus an...

How to graph the resultant vector from the difference of two vectors
Learn how to add/subtract vectors. Vectors can be added, subtracted and multiplied. To add or subtract two or more vectors, we simply add each of the corresponding components of the vectors.

Given the magnitude and direction of a vector find it's components
Learn how to determine the magnitude and direction of a vector. The magnitude of a vector is the length of the vector. The magnitude of a vector is obtained by taking the square root of the sum of the squares of the components of the...

cross product moment example
Calculating the moment of a force can be quite tricky (especially in 3 dimensions). A good way to solve these problems is to use the cross product noting that *M* = *r* x *F*

relative velocity derivation
This is an introduction to relative velocity. There is an animation at the end which helps highlight that the motion of a rigid body can be split into both rotational and translational movement. I also show (informally) that the velocity...
