Curves,curve with the curve mapping itself. The parametric representation of (the graph of) a space curve is not unique. The circle above can also be represented by .(.) = (1 −. .)/(l + .) and .(.) = 2./(l + .) for −∞ < h ≤ ∞; this follows by introducing tan(./2) for ..

Mathematical Preliminaries,inner product (also known as the dot product) and vector cross product operations. Although this episodic material is no substitute for previous exposure, it may be helpful to have some basic results presented here.

Curves,y .(.) = cos(.) and .(.) = sin(.) for −π < . ≤ π; the argument . is called the . of the curve mapping .. The graph of . is thus (.(.),.(.)) | .(.) = cos(.), .(t) = sin(t), −π < t ≤ π. In general, a . is a mapping from some interval [.,.] , . into .. A . is a mapping from some interval [.,.],. into .
