How to plot parametric plot (cos³ t , sin³ t )

graph sin t + cos (sqrt(3)t)

plot3d Re[sin(1/(x+i y))] from x = -1/pi to 1/pi, y = -1/pi to 1/pi

plot3d Re[tan(1/(x+i y))] from x = -1/pi to 1/pi, y = -1/pi to 1/pi

plot3d Re[cot(1/(1.5x+i y))] from x = -1/pi to 1/pi, y = -1/pi to 1/pi

plot3d 1/(x^2+ xy+ y^2) from x = -1/pi to 1/pi, y = -1/pi to 1/pi

plot 3d (-x^2-y^2)

Three dimensional plots typically display a surface defined by a function in two variables,
z = f(x, y)
