  1. 14-1 Graphing Trig. Functions (Day 2)

  2. Find the Following Values using Your Calculator: = undef. • tan (-π/2) • tan (-π/4) • tan (0) • tan (π/4) • tan (π/2) The graph of y= tan (x) is different from the other graphs: = -1 = 0 1 = 1 = undef. Period: π - 1 Asymptote Asymptote

  3. Properties of y = atan (bx): y = atan (bx) is also periodic. y = tan (x): a tells you what points to graph on the y-axis.

  4. Ex 1: Graph one cycle then label the asymptotes and the period y = 4tan 3x a = 4 b = 3 4 The first point will be on the origin. The next 2 points will be half way in between the origin and the asymptote. Use “a” as a measure of height. - 4

  5. Ex : Graph one cycle then label the asymptotes and the period. y = ½ tan πx a = ½ b = π ½ = 1 -½

  6. Exit Slip: Graph one cycle then label the asymptotes and the period. y = 3 tan 2πx
