"Characteristics: R:-2.5 ≤ y ≤ 7.5
minimum at x=200°
period is 270°
A) Sketch 2 cycles of the function.
Note: Remember to label the 5 main coordinates of each cycle, and the equation of axis.
B) Develop 2 equation based on the sketch above, and explain/show how you figured out each part of the equation:
(i) cosine function (in radians)
(ii) negative sine function (in degrees)"
