### Math Warm Up Series

 Has it been years since your precalculus course? Does the phrase "completing the square" strike fear in your heart? Here are some videos that can help you review topics needed in your math courses. Algebra success at any level of math depends upon good basic algebra skills. Whether you're preparing for the algebra test or just reviewing, these videos will help you brush up on algebra. We review polynomials, factoring, exponents, and more, all starting from the fundamental axioms of algebra. Good pre-calculus skills are a must for Math 1a and beyond. Trigonometric functions are some of the important functions studied in calculus. A trigonometry refresher is for those who have studied trig but might be a little rusty. Would you feel comfortable explaining logarithms to your roommate? Do you keep a picture of the graph of y = ln x in your head? If your answers are no, watch this video to help get yourself on more solid ground. A clip on conic sections covers conic sections (circles, parabolas, ellipses, and hyperbolas), which have been studied since the time of the Greeks. Has it been a while since you took Calculus AB? From tangent lines to derivatives, and from integrals to the Fundamental Theorem of Calculus, what are the big ideas? How many angels can dance on the point of a needle? Could Zeno be right that motion is impossible? Limits help to answer these philosophical questions. Complex numbers are magic. The complex numbers clip deals with things like like how to compute (-1)i or log(-1). This video is especially useful for those planning to take Math 21b. The Problem solving part gives you a mental toolbox to help think like a mathematician and figure out problems that you do not immediately know how to solve. Take advantage of all the math help resources available to you! There are strategies for getting help from your textbook, instructors, course assistants, and classmates. Do you know how to use a graphing calculator for things besides graphing? Have you seen or used Mathematica before? A video demonstrates the powerful software available to you.
