Weekly Quiz #5
Chapter 10 & 11
Show ALL work on separate paper; not on this sheet, not in your green book. Your assignment
will not be accepted if work is missing, sloppy, or incomplete for any question. Show as much work
as possible, including diagrams and formulas when applicable. Lack of effort will result in a low or
zero grade.
Box each final answer for each question.
A reference sheet has been provided for you on the second page.
You do not have to print either of these pages, but of course you can if that helps you.

Functions of the Sum of Two Angles
Law of Cosines
sin (A + B) = sin A cos B + cos A sin B
cos (A + B) = cos A cos B – sin A sin B
tan A + tan B
tan (A + B) = ___________
1 – tan A tan B
sin 2A = 2 sin A cos A
cos 2A = cos2 A – sin2 A
cos 2A = 2 cos2 A – 1
cos 2A = 1 – 2 sin2 A
