1D. A given sinusoidal function has a period of 3, an amplitude of 'i', and a maximum at [I]. 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 = I] and Eat. 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 1ralues to 3 places. [E marks] 12. How many different sinusoidal functions can be written that have a period of 33:, an amplitude of 1: and a minimum at {2, 3}? [1 mark]
