I need help with these math problems

timer Asked: Mar 4th, 2013

Question Description

1) If sin theta = -1/2, find all the possible values of theta where 0 <= theta <= 4 pi I am lost on how to solve this. 2) If tan theta = 84/13, and the terminal side of theta lies in quadrant III, find sin theta I know for this tan theta= r/x which equals 84/13. Do you do the pythagorean theorem to find y since sin theta= r/y? Please help me solve this 3) Graph y= -4cos(2x+pi) for at least 1 period. Label the amplitude, period, phase shift, your axis, and the points you're plotting. For this question I know the amplitude is 4. I'm having problem solving the period, and finding the points I will use to graph. Please help
