The video will work on the computer.
I know I had several brain farts, I hope it still helps, regardless.

Asymptotes (9/2)
An asymptote is a line that the graph of a function approaches but never touches.
Asymptotes can be solved
- Numerically (looking at a table)
- Algebraically (solving for values)
- Graphically (viewing a graph)
There are 3 types of asymptotes
Vertical (x=a number)
Horizontal (y=a number)
Oblique (y=x)
Rational Function Theorem (9/2)
Vertical Asymptotes (VA)
- VA occurs where x=a number
- The graph of the function will approach x=a number, but will never reach
- Algebraically Graphically
Horizontal Asymptotes (HA)
- HA occurs where y=a number
- The graph of the function will approach y=a number, but will never reach
- Algebraically Graphically
Exponent Rules (9/2)
Trigonometric Values (2/15) Main trig functions: sine, cosine, tangent have key trig values at angles 0, 30, 45, 60, and 90. Useful for 45-45-90 and 30-60-90 triangles. Trig values MUST be memorized. There's an easy hand trick linked below to learn them, but do NOT use it as a crutch. It's a bit of reading, but it is well worth understanding. http://mathrescue.blogspot.com/2012/08/trigonometry-evaluating-base-angles.html |

Examples:
1. cos(135)= -sqrt2/2
2. sin(210)= -1/2
3. sin(-60)=-sqrt3/2
4. tan(45)= 1
5. cos(300)=-1/2
1. cos(135)= -sqrt2/2
2. sin(210)= -1/2
3. sin(-60)=-sqrt3/2
4. tan(45)= 1
5. cos(300)=-1/2
