PG 425
To make the graph of the basic tangent curve, we first make a table of angles & cosine values from the unit circle....
(angle)tan
(angle)tan tan ....now let's make our graph.
How does this compare to the graph in our "Solve It"?What is the period?
More Practice: Sketch 2 cycles of the following graphs: (on homework do 2 cycles)
a) 𝑦𝑦 = 𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝜃𝜃 b) 𝑦𝑦 = tan −𝜃𝜃2
c) 𝑦𝑦 = 𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝜃𝜃
Extra PracticeWhat is the value of the function at 30° and at 2𝜋𝜋
3radians?
a)𝑦𝑦 = 𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝜃𝜃
b) 𝑦𝑦 = 50𝑡𝑡𝑡𝑡𝑡𝑡𝜃𝜃
Extra Practice
Solve each equation in the interval from 0 𝑡𝑡𝑡𝑡 𝑡𝜋𝜋. Round your answers to the nearest hundredth.
a)𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡 = 3 b)𝑡𝑡𝑡𝑡𝑡𝑡𝜃𝜃 = −3 c) 6𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡 = 4
