1. 6-3 Trigonometric Graphing
Day 2
Mrs. Cassidy – could we please see the others? Please please please

2. The other 4 Get your chart out again! Graph y = tan x Graph y = cot x
Graph y = sec x
Graph y = csc x

3. How do trends hold here?
They will hold pretty much the same way – seeing shifts left, right, up, down and seeing changes in periodicity.
Lets look at the following graphs:

4. Basic Truths
The period of both y = sec x and y = csc x is 2π. (makes sense, right?)
The period of y = tan x and y = cot x is π.
We really don’t talk about amplitude of these four functions.

5. My Method for Tan/Cot/Sec/Csc
Determine 3 New Asymptotes
Set Argument = Old Asymptotes
and solve for x
Find 2 midpoints
Plot these 2 points
Sketch the functions according to what they looked like before.

6. Examples
Graph the following completely 1. 2. 3.
