Locus of the point u=cos(z) is illustrated with z on a conic centred origin. Move point F , point D , point E to alter the conic.
point I represents complex number u
point H represents complex number z
other variables are unnecessary, a trial in layer(1) with straight line instead of conic
some other loci are included
illustrate the property of the locus corresponding to different kinds of conic.
