Ch 6B Sec(x) and csc(x).notebook
October 03, 2013
Graphing y = sec(x) and y = csc(x)
Graphing Secant and Cosecant (finishing up)
Learning Targets: I can generate the graphs of tangent, cotangent, secant, and cosecant with transformations
I can determine the domain, range, period, and amplitude of the graphs.
y = sec(x)
CCSS: F­TF.5 DOK: 1, 2
Things to remember about y = sec(x):
Writing the equation of a sinusoid.
Learning Target:
Sec(x) has tails­­­like tan(x)
Asymptotes are like tan(x)
It is the reciprocal of cos(x) I can write the equation for a sinusoidal function given a graph or specified information.

Ex 1) y = 3 sec x
y = csc(x)
Things to remember about csc(x):
Does not have tails
Asymptotes are like cot(x)
Reciprocal of sin(x)

Ex 4) y = 4 csc (1/2 x)
So... the question we left off with yesterday was.....
When would the asymptotes be at the even pi's?
Hmmmmmmm.......

Assignment: Worksheet
The first 6 are the parent functions. MUST know these for the test.
You have 13 minutes to work and then we are moving onto sinusoids. Sep 27­3:36 PM

Assignment: p. 433 #38­50E, 64­70E
When the book says "phase shift" that is a horizontal shift.
Also if it says " phase shift 3" that means right three.
