This free course is intended to provide a core of the mathematical skills that are used in college-level science, technology, engineering, and mathematics (STEM) courses. It is not completed and will be completed as time permits.
In these days of standardized tests, geometry, algebra, and trigonometry are integrated. There are arguments for this pro-and-con. Formal proofs and derivations tend to be sacrificed for the sake of applied and integrated problems. That's fine as long as the concepts and formulas aren't thrown at a student, "Here, use this," without them knowing where it comes from. The course is a guide while learning in class (not a substitute for class) OR a quick review of the math we all need to brush up on from time to time. I have an agenda with it: to refer to these lectures, or even present them in class, when STEM students aren't on board with what's assumed in a college course.
