(given any three parts)
•SSS
– Given 3 sides
1. Use Law of Cosines to find other 2
angles
2. Find 3rd angle by
180 minus two angles
•SAS
–
Given 1 angle & other 2 sides (not opposite side)
1. Use Law of Cosines to find the 3rd side and 2nd angle
2. Find 3rd angle by 180
minus two angles
•AAS or ASA – Given 2 angles & 1 side
1. Find 3rd angle by 180 minus two angles
2. Use Law of Sines to find other 2 sides
•SSA
– Given 1 angle & 2 sides (one side opposite to the angle)
1. Using Law of Cosines:
•Find the 3rd side, using the equation of the given angle
•This will give a quadratic equation with graph that has 1, 2, or no solutions.
2. Use Law of Sines, determine if 1, 2, or no ∆s:
•Given obtuse angle A:
1.a > b - one triangle
2.a < b - no triangle
•Give acute angle A:
1.a > b -
one
triangle
2.a < b
•a
> h (h < a < b) - two triangles
•a
= h - one triangle
•a
< h -
no triangle

Rational Functions/Equations
Look here for videos on Rational Functions
Domains:
rational expressions and domains - these methods for finding domains also apply to equations
finding the domain of a function - only the first example in this video is a rational function
Finding Asymptotes:
vertical asymptotes
horizontal asymptotes
slant asymptotes
examples - also has links to how to find all three types of asymptotes
Graphing:
example of graphing
(please use this video to explore more examples of graphing...)

Complex Numbers
Watch these videos and copy down at least one problem from each to get a Bonus point on the next test for each one you watch and write down the problems of. (You only need to write down one problem from each video since they are so repetative, but you must copy down a different kind of problem from each.)
