7.9 Graph of Tangent Function

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

General Tangent Curve middle point of graph

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

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
