FC: A YEAR IN REVIEW | Lessons learned in Math 172: Precalculus Trigonometry
1: Vectors | In order for vectors to be equivalent they must have the same distance, slope, and direction.
2: Law of Cosines | Formulas
3: Law of Sines
4: Exponential Functions | As the x-inputs increase, the curve gets closer and closer to this line. However, it does not cross it. | Read the graph from left to right. | If the exponent is negative it curves down to the right. | If the exponent is positive it curves up to the right.
5: Exponential Properties | Increasing if a > 1 | Decreasing if 0 < a < 1
6: Converting Logarithms
7: Properties of Logarithms
