Given that cos(θ ) = − 4 5 and that csc(θ ) < 0, construct a reference triangle and use it to compute the values of all other trigonometric functions of θ . 3. a ferris wheel is built such that the height h (in feet) above ground of a seat on the wheel at time t (in seconds) can be modeled by h(t) = 53+ 50sin � π 10 t − π 2 � . (a) what is the period of the function which models the height? give units. briefly explain what the period tells you about the ride. (b) what is the amplitude of the function which models the height? give units. briefly explain what the amplitude tells you about the ride. (c) what is the vertical shift of the function which models the height? give units. briefly explain what the vertical shift of the function tells you about the ride. 4. for each of the following transformations of the sine and cosine functions, determine (i) the amplitude, (ii) the period, (iii) the horizontal (phase) shift, (iv) whether the graph is reflected across the x-axis, (v) the vertical shift, and (vi) where the five key points from the original graph end up. then graph two full periods of the function on the blank axes provided.
