CalcPlot3D workshop at RMU

On August 7-10, 2016, nine engineers, mathematicians, developers, and educators met at Robert Morris University to develop new CalcPlot3D explorations, to begin importation of explorations to WeBWorK, and to continue research on student understanding of multivariable calculus concepts.  The new … Continue reading

A 3D printed knot

Here are two photos of the 3D model of the parametric surface: x(u,v)  = cos(u)*cos(v)+3cos(u)*(1.5+sin(u*5/3)/2) y(u,v) = sin(u)*cos(v)+3sin(u)*(1.5+sin(u*5/3)/2) z(u,v) = sin(v)+2cos(5u/3)
