#Pre calculus for dummies irl how to#

Have no fear! We’re here to help you cross the bridge (toll free).īecause you’ve probably already taken Algebra I, Algebra II, and geometry, we assume throughout this book that you already know how to do certain things. You keep on building until the end of the course, which doubles as the beginning of calculus. You see some brand-new ideas, but even those build on the material you’ve seen before the main difference is that the problems get much harder (for example, going from systems to nonlinear systems). In its scope, you review concepts you’ve seen before in math, but then you quickly build on them. Pre-calculus is the bridge (or purgatory?) between Algebra II and calculus. Chapter 1 Pre-Pre-Calculus In This ChapterĪrrow Refreshing your memory on numbers and variablesĪrrow Accepting the importance of graphingĪrrow Preparing for pre-calculus by grabbing a graphing calculator Lastly, we show you how to deal with exponential and logarithmic functions. We also explain how to graph complex polynomial and rational functions. Then we move on to polynomials and review how to solve polynomials using common techniques, including factoring, completing the square, and the quadratic formula. From there, we review functions - from how to graph them by transforming their parent graphs to how to perform operations on them. The chapters in Part I move through a review of working with real numbers, including the ever-elusive radicals. Perhaps most importantly, it identifies the most common mistakes students make in algebra so you can conquer those before moving on to higher-level concepts. This part pulls together and expands on those algebra concepts. Ī major goal of pre-calculus is to bring the big ideas of algebra to the surface and sharpen the skills most needed for calculus.
