The following expert technique for inclass Exercises and Exams will develop your personal power
and insight to solve problems presented to you on homework, quizzes, exercises, or exams.
1. A
full
appropriate diagram or physical sketch must appear as the
starting
point 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
v
i
, launch
angle
θ
, and freefall acceleration magnitude
g
.
For instance, substitute (–
v
i
cos
θ
) for v
ix
just
after it first appears in an
OSE
, but keep
v
i
cos
θ
through to the end before evaluating
numerically.
