# Complex Numbers, Radians, and more!

Laura Shears (a fellow Michigander) has a great site of resources for the precalculus level called LSquaredMath. I haven’t covered much precalculus material on the blog because I haven’t taught precalculus for a while, but her latest update reminded me that I should pass along her website to you!

Laura has been working with Flash for a few years now, creating animations for mathematics. She suggested to me that I should attend the MAA PREP Flash course (which I did last summer) and it was my attendance that ultimately inspired the blog. Anyways, back to the story … Laura has been working on making all her material SCORM-compliant (that means it plays nice with the gradebooks in LMS platforms like Blackboard, WebCT, etc.).

Complex Number Graphing (both Cartesian and Polar)

Addition of Ordinates (if you’ve got a Smartboard, you’ve got to try this one in class, here’s a little video demo of how I’d use it in class)

Radian Measure and the Unit Circle (a great review exercise for Calculus Students that don’t know their Trigonometry)

You will notice that Laura lets you use all of her material from the website for free, but does charge for a SCORM compliant version. Before you start complaining about that – note that Laura is an adjunct instructor and building this stuff takes a LOT of time.

If you’re interested in creating SCORM compliant FLASH material yourself, you should take a look at Laura’s help page for SCORM here.
