19.7.1  2D parametric curve

Examples

plotparam(cos(x)+i*sin(x),x)

or:

plotparam([cos(x),sin(x)],x)
plotparam(sin(t)+i*cos(t),t=-4..1)

or:

plotparam(sin(x)+i*cos(x),x=-4..1)

or, with t-=4,t+=1 in the graphic configuration:

plotparam(sin(t)+i*cos(t))
plotparam(sin(t)+i*cos(t),t=-4..1,tstep=0.5)

or, with t-=4,t+=1 in the graphic configuration:

plotparam(sin(t)+i*cos(t),t,tstep=0.5)
