Section6.6Summary of Functions

In this unit we've covered a lot of different function types. Be sure you can recognize each one both from its functional form and its name. The following list provides a summary of the unit.

  • y=f(x) or f:RR (functions of a single variable)

  • r(t)=(x,y) or f:RR2 (parametric curves)

  • r(t)=(x,y,z) or f:RR3 (space curves)

  • r(u,v)=(x,y,z) or f:R2R3 (parametric surfaces)

  • z=f(x,y) or f:R2R (functions of two variables)

  • z=f(x,y,z) or f:R3R (functions of three variables)

  • T(u,v)=(x,y) or f:R2R2 (2D transformation)

  • T(u,v,w)=(x,y,z) or f:R3R3 (3D transformation)

  • F(x,y)=(M,N) or f:R2R2 (vector fields in the plane)

  • F(x,y,z)=(M,N,P) or f:R3R3 (vector fields in space)
