Re: Secant/Cosecant Graphs-
The graphs of co-secant and secant graphs are both similar and different.
1. A co-secant graph is a shift of 90 degrees or pi/2 to the right of a secant graph.
2. The asymptotes for a secant graph cut through the center of the parabolic-structure of co-secant graphs.
3. The asymptotes for co-secant graphs cut through the center of a secant graph.
4. When a sine graph's x-value is zero, the x-value for a secant graph is also zero.
5. When the x-value for a cosine graph is zero, the x-value of a co-secant graph is also zero.
6. All odd intervals of pi have the secant graphs opening downward.
7. All odd intervals of 3pi/2 have co-secant graphs opening downward.
8. All even intervals of pi have secant graphs opening upwards.
9. All even intervals of 3pi/2 have co-secant graphs opening upwards
Question: Is there an algebraic way of modeling "all odd intervals of"
"all even intervals of"
Hint: It may involve k's and Z's
