Students, do you have a TI-83 or 84? If so, you've stumbled on a tool that can help you easily boost your ACT math score.Are you afraid you'll forget the distance formula or the Pythagorean Theorem? Fed up with matrices and quadratic equations? Or do you just want to improve your accuracy and speed on the ACT math section? Believe it or not, there are no rules banning the use of calculator programs stored in your TI 83 or 84 on the ACT. With some simple programming instructions, you can have your calculator calculate complex equations for you. You'll save time, and you can shift that time over to other problems you may not be able to tackle otherwise. This packet is a collection of the TI calculator programs that are both extremely easy to program (even for the tech-phobic) and most helpful on the ACT. We'll give you step-by-step programming directions and show you how to use these programs on dozens of real ACT questions. This book includes: > Distance formula > Slope finder > Pythagorean Theorem > Quadratic equation solver > How to solve that scary-looking matrix problem ... and much more
