1. 7.9 Graph of Tangent Function

2. Graph of y = tanx
x y 1 –1
Period = 𝝅
Amplitude = not defined

3. General Tangent Curve
middle point of graph

4. Graph of y = cscx Reciprocal of sine Graph sine first
csc x is und when
sin x = 0
csc x = 1 when sin x = 1
csc x = 2 when sin x = ½
csc x = –1 when sin x = –1
csc x = –2 when sin x = –½ 1 –1
Amp is undefined
Period = 2π

5. Graph of y = secx Reciprocal of cosine Graph cosine first
sec x is und when
cos x is 0
sec x = 1 when cos x = 1
sec x = 2 when cos x = ½
sec x = –1 when cos x = –1
sec x = –2 when cos x = –½ 1 –1
Amp is undefined
Period = 2π
