Calculate the Moon's Synodic Period
The Attempt at a Solution
I am supposed to plot a graph of Time(y-axis) against Phase (x-axis), where phases is not a sin curve but a straight line, because we are adding upwards, ie from a new moon to ful is from 1/8 -> 8/8, then it goes back down, but the phase plotted continues to go up, from 1 1/8 -> 2, and so on, giving a nice straight line. Now we are supposed to plot a straight line through the data, which I have done in Excel, and it has given me a gradient of 0.0713.
Can anyone give me any clues how you are supposed to get the period from this?
Thanks in advanced,
