Determine the values of 0 if - 04 given that sin 0 = -0.05 [5 marks] 7. Why do radian measurements not have a unit indicated? [2 marks] 8. A given sinusoidal function has an amplitude of 8, an axis at y = 12, a period of 9, and a maximum at x=3. Determine an equation for the function, and find all intersections of the function and y = 16 between x = -5 and x = 12. [8 marks] 9. Using electronic graphing tools, graph y = 2 sin(3[x4]) +5 and y = 2 csc(4x-3) - 1 on the same axes. Find all points of intersection of the two functions between - and , with answers to 2 decimal places. Include an image of the graphs in your response. [6 marks] 10. A given sinusoidal function has a period of 3, an amplitude of 7, and a maximum at (0, 2). Represent the function with a sine equation and a cosine equation. [4 marks] 11. Provide a trigonometric equation. Considering only the space between x = 0 and 2, the equation must only have solutions at x = 1 and x = 2. Explain your thought process and the work you did to create the equation. You may round decimal values to 3 places. [6 marks]
