I'm stuck on a question from my calculus homework...T_T Here's the question... There is a large clock at the front of the lounge on the paddle steamer. The hour hand is 28 cm long and takes 12 hours to rotate once. At 2 o'clock the tip of the hour hand is 195 cm above the floor. There's no equation given instead there's an image... (please view attachment for the image given) The question is write a trigonometric equation that will model the height of the top of the hour hand above the floor. Where h = the height above the floor in centimetres, t = time since 12 O'clock in hours and the angel is measured in radians. What I do know is that it must either be a cos or sin graph... So must be in the form of h=A sinB(t+c)+D or h=A cosB (t+C)+D I think the period is 12 hours...therefore if it is 12 hours the frequency must be pi divided by 6. I don't understand how to work out the rest though... please help?
