It is swung 2.75 full circles. How far has the plane traveled? 7) Find the 6 trig functions for the standard position angle θ whose terminal side goes through (-5, -12). 8) Given sin(t) = ¾ and cos(t)<0 find the following. a) cos(t) b) csc(90° - t) c) tan(t) e) csc(t) d) cot(t) 9) Given f(x) = 2sin(2x) + 3cos(3x), is f periodic? Is f a sinusoid? 10) Graph two periods of each of the following. (Check your answers using your calculator.) a) y 2 cos( x 3 ) x 3 b) y sin 2 2 4 c) y 2 tan( x ) 4 d) y cot(2 x) x e) y 3csc( ) 1 3 2 f) y 4sec(2 x ) 2 3 g) y = 2x sinx h) f(x) = 3x – cosx 11) (Use the calculator to do the number crunching for this one. The numbers are uglier than on the test) The number of hours of daylight, d, in Hartsville can be modeled by , where t is the number of days after March 21. The day with the greatest number of hours of daylight has how many more daylight hours (rounded to the nearest tenth) than May 1? (March and May have 31 days each. April and June have 30 days each.)
