Wed, 02 Oct 2019 07:48:07 +0000<![CDATA[You can create the surface with Surface(sin(t), cos(t), p*(1+sin²(t)*cos(t)), t, -pi/2, pi/2, p, 0, 1) In this p is the second parameter from 0 to 1, to cover the height between the function and the curve as a surface. For lenghts of curves and areas of surfaces you have to formulate and calculate the integrals yourself. GeoGebra doesn't do that for you. chris]]>
