Half Chasing The Sun

Degrees of freedom: 2*

This trick involves a smaller and a larger circle traveling within the X-Y plane in the global reference frame, so there are 2 degrees of freedom

*Assuming poi is a point mass. For more information on planes and this assumption, see the technical info page here

Expected and observed frequencies:

Two major frequencies are observed, one at the base rate of ~1Hz which correlates with the larger outer circle the poi travels during the trick, and a second higher frequency of ~2.3 Hz that correlates with the inner smaller circle the poi travels during the trick

Equations to characterize trick:

• X = cos(t) + cos(2 t + π)
• Y = sin(t) + sin(2 t + π)
• Z = 0
