Develop a function to produce an animation of a parti- cle moving in a circle in Cartesian coordinates based on ra- dial coordinates. Assume a constant radius, r, and allow the angle, 0, to increase from zero to 2n in equal increments. The function's first lines should be function phasor(r, nt, nm) % function to show the orbit of a phasor % r = radius % nt = number of increments for theta % nm = number of movies Test your function with phasor(1, 256, 10)
