a) Sketch the graph of the vertical position of the tip of the hour hand versus the angle through which the hand turns for a time period of 72h. Assume that the hour hand starts at 9.

C)How many cycles appear in the graph in part a)

I have no idea how to drraw this please guide me I really need your help:( Thanks!

**Reiny**, Wednesday, March 6, 2013 at 6:10pmcall your horizontal axis the t axis (usually the x-axis)

call your vertial axis the y axis

Your graph should be a sine curve, where a complete sine curve fits into 12 hours.

So label you t axis in hrs , with its end at 72

Since 72/12 = 6 , you will have to draw 6 complete sine curves

you want y = 0 when t = 9, plot that

you want y = 6 when t = 10 , plot that

you want y = 12 , when t = 12 , plot that, it will be your maximum point

you want y = 6 when t= 2

you want y = 0 when t = 3

you want y = -6 when t = 4

you want y = -12 , when t = 6, this is your minimum point.

join you points with a smooth sine curve, and repeat to t = 72+9 or 81, for 6 complete cycles of the curve.
