Welcome to Alex Derives Stuff! Here you will eventually find lots and lots of entries of me, Alex, deriving things. The derivations will range from the basic (such as the Binomial Theorem) to the advanced (for me, anyway) to the strange and weird and fun. My hope is to provide a free online reference for the background material required for learning math, and learning it well. Each post will provide links to prerequisite material, practice problems, and anything else that might be relevant to learning the material. Please let me know in the comments section if there is anything you would like to see derived, or if you have questions, suggestions for improvement, or possibly interesting links to related sites. this is an experiment in online supplementary education, and I fully expect problems to arise as I post things, so constructive criticism is welcome!
Enjoy the derivations!
