Homework 8

General Comments

• Problems are taken from the textbook unless otherwise noted.
• For full credit, provide context for each problem, show all calculations, and explain your work/answers.
• Numbers and/or algebra by themselves are not enough.
• You will lose a significant amount of credit if you do not show enough work/context for your answers.
• Precision is very important. You cannot skip steps, make guesses, or use flawed logic. Any of these things can lead to incorrect answers.
• Homework assignments must be very neatly written or typeset (e.g. using Word or OpenOffice).
• You must indicate any assistance you had on an assignment as specified on the Policies page.
