Check word problems from yesterday.
p.296 (75, 76)
Discuss that the Tangent function is created by the quotient of Sine over Cosine.
Since the Cos can equal zero, this influences our Domain and also introduces vertical asymptotes to the graph
Show how a sin/cos Unit Circle can easily be used to find the tan values at the main angles.
Note that the Period of Tan(x) is pi... look at how the positive and negative sin/cos values in the 4 quadrants make this so. Remind them that the period of the Tan function is pi ---> half that of the sin/cos -2 pi.
Quickly look at the graph of the tangent and cotangent functions
Discuss how to indicate that the vertical asymptotes are given by x = pi/2 + npi
Discuss the Domain being x not equal to pi/2 + npi
Discuss how the Range is all Reals (pos infinity to neg infinity)
