The second semester of PreCalculus brings with it a host of very different ideas, presented at a very quick clip. Vectors, Combinatorics, Logarithms, Compound Interest, Polar Functions, Probability, Matrices… the list just keeps going, and it’s going to be our job this semester to break down each section into its essential concepts, and develop student study sheets so that, come May, the hard work for preparing for the final will already have been done, and the students won’t be faced with the task of trying to cram twelve totally different and long since forgotten units back in their heads.
