EXPERT TECHNIQUE FOR SOLVING PROBLEMS IN INTRODUCTORY PHYSICS The following expert technique for in-class Exercises and Exams will develop your personal power and insight to solve problems presented to you on homework, quizzes, exercises, or exams. 1. A fullappropriate diagram or physical sketch must appear as the startingpoint of your solution. 2. In any derivation, your mathematics must begin with a correct rendition of an equation in the list of Official Starting Equations(OSEs). (However, this need not be followed for purely mathematical problems, such as those dealing solely with graphing or trigonometry.) 3. During steps of a derivation after the OSE, a physical quantity must eventually appear as an algebraic symbol representing a magnitude, e.g. distance d, height h, initial speed vi, launch angle θ, and free-fall acceleration magnitude g. For instance, substitute (– vi cosθ) for vixjust after it first appears in an OSE, but keep vi cosθthrough to the end before evaluating numerically.
