I need help with this equation that reresents a windmail. the top is point p. y=2cos(30x)+6 I need to find out how long it will take for point p to reach the height 4.5 meters for the sixth time. it takes 12 seconds to make a full rotation. If you can dont give me the answer for 4.5, use a different number if you can.
