Hey all, recently saw this video on the batman curve, designed by a high school teacher that draws the batman logo. He combined an ellipse, straight line graphs and some other sinusoidal wave then forced the functions to be imaginary at certain points to hide the unwanted bits. question, how does one combine those graphs? and secondly how does one force a graph to be imaginary at certain points without the bits you want to show being shifted? Any help apreciated.
