Warm Up Jan. 26th 1. Evaluate the following:

a. tan(0) b. tan(π/4) c. tan(π/2) d. tan(3π/4) e. tan(π)f. cot(0) g. cot(π/4) h. cot(π/2) i. cot(3π/4) j. cot(π)

2. Write an equation for the graph below.

Homework Questions??

Remember…

csc x?

1

How are the graphs of sin

and csc related?

sec x?

1

How are the graphs of cos

and sec related?

Graph: y = 2sin(4x)

Graph: y = 2csc(4x)

Graph: y = 1 – 4sec(x – π/6)

Graphing tangent…Where is tangent undefined???

What is the period of y = tan x?

Graph: y = 2tan(3x)

Graph: y = - ½tan(x + π/4)

Graphing co-tangent…Where is cot undefined???

How is the graph of y = cot x related to the graph of y = tan x?

Graph: y = 2cot(4x)

Graph: y = - cot(2x + π/4)
