    Torsion of a curve is usually taught via formulas involving the cross-product of the velocity and acceleration vectors.

    With a CAS animation, we may watch a point travel along a curve, and view the length of the binormal change, coupled with the twisting of the TNB frame.

    With a VR animation, we may actually ride along the curve and experience the torsion.

    Of course the formulas are required for mathematical analysis, but what are the benefits for students in experiencing the changes in torsion? Does this effect the way we teach TNB analysis?

  • How Will Virtual Reality Change Vector Calculus?
    One goal of this book is to address this question, via exploring many of the topics of three-dimensional calculus using the power of virtual reality a la VRML. Until recently, all of multivariable/vector calculus was taught algebraically. Now many courses utilize computers via computer algebra systems and graphing tools to visually investigate the geometry of curves and surfaces in 3-space. Virtual Reality/VRML holds many possibilities for extending the visual investigation experience. The incorporation of CAS's forced many changes in the curriculum for 3D calculus over the last five years; we ask: how will VR change it in the next five years?
