  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. Ex 1) Graph Factor out b Check Period: b c a d = = = 2 = 0 2 (middle) –2 Per = IL: Check a point:

  5. Ex 2) Graph Check Period: b c a d = 1 = = –3 = 0 3 (middle) –3 Per = π IL: Check a point:

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

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