Evaluate the following expressions. Your answer must be an exact angle in radians and in the interval [0, ] Example: Enter pi/6 for T 6' (a) cos 2 3 (b) cos (1) (c) cos = 2 2 = = Find all solutions to 2 sin(0) = -3 on the interval 0 0 < 2 0 = Give your answers as exact values, as a list separated by commas. 3 1 15-14-13-12-11 -10 -9 -8 -7 -6 -5 -4-3-2-1 -1 -2 -3 2 4 6 18 9 10 11 12 13 The curve above is the graph of a sinusoidal function. It goes through the points (-13,0) and (1,0). Find a sinusoidal function that matches the given graph. If needed, you can enter =3.1416... as 'pi' in your answer, otherwise use at least 3 decimal digits. f(x) = Given the equation y = = 5 sin(2(x 7))+4 - The amplitude is: The period is: The horizontal shift is: units to the Select an answer The midline is: y =
