Recreational Math: Math Videos

Most of this series is actually calculus, not recreational math. You will learn the power, product, and quotient rules for derivatives, and use calculus to solve optimization problems like minimizing cost and maximizing volume. You will also study limits, the mean value theorem, and Riemann sums. The series ends with three playful Vi Hart videos about sound, a strange number called wau, and the geometry of a cartoon pineapple. You should be comfortable with algebra and have started calculus.
