DIRECTIONS:   In this applet, you create a curve that is piecewise quintic polynomial. You need to specify six points for the first quintic curve, and then three for each additional arc. The points are labelled p_i where i=0,1,...,3n+2 and n is the number of arcs given. The curve is specified according to the following scheme: the point p_3k specifies the point on the curve when t=k, the point p_3k+1 specifices the derivative of the curve at p_3k by specifying the vector p_3k+1 - p_3k, and the point p_3k+2 specifies the second derivative of the curve at p_3k as p_3k+2 - p_3k.
