Problem questions (i.e. questions where some calculation is required) must be presented in the manner outlined below to receive full credit. The purpose of this structure is to help you organize your thoughts and correctly synthesize concepts given in lecture. Each underlined section should actually be visible on your homework (see example above).
A. A brief statement of the problem. This should remind you what the problem is about when you revisit it later, and will help you read the problem statement carefully. Save numerical values for the “given” section.
B. Given: List pertinent information from the problem, including numerical values (give units) and any other “clues” you think will help you solve the problem
C. Find: The specific objective of the problem. Usually a variable to solve for, with required units.
D. Know: Guiding equation or concept you learned in lecture that will allow you to solve the problem. This is the key to the solution!
E.
Solution: Arrange
what you were given and what you know into a form that will allows
you to solve for what you must find.
Carry units through all calculations; a number by itself means nothing!
Use reasonable significant digits. Box your final numerical answer
and be sure to include units and
use reasonable significant digits.
Tips: Leave space between your
calculations, write neatly, use one side of the paper, and show
all your work. I cannot give
partial credit if I can’t read your work.
Even if you can’t solve the problem write
down what you know to get full partial credit.
