2. Deka needed to determine the y-coordinate of a point that had turned 6° on a unit circle. Deka looked at the calculator and exclaimed, "Oh no! My calculator is not in degree model" sin(6) -0.2794154982 (a) Explain how you can tell from the calculator's result that the mode setting is for radians. *Include a well-labeled unit circle sketch to aid your response. (b) Draw a new unit circle. On this circle, sketch the actual turn angle whose y-coordinate was calculated when Deka used their calculator and saw sin(6) -0.2794154982 (c) Now do the actual conversion to determine the exact and approximate degrees for the turn Deka evaluated on the calculator. All work must be shown.
