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:R→R (functions of a single variable)
→r(t)=(x,y) or f:R→R2 (parametric curves)
→r(t)=(x,y,z) or f:R→R3 (space curves)
→r(u,v)=(x,y,z) or f:R2→R3 (parametric surfaces)
z=f(x,y) or f:R2→R (functions of two variables)
z=f(x,y,z) or f:R3→R (functions of three variables)
→T(u,v)=(x,y) or f:R2→R2 (2D transformation)
→T(u,v,w)=(x,y,z) or f:R3→R3 (3D transformation)
→F(x,y)=(M,N) or f:R2→R2 (vector fields in the plane)
→F(x,y,z)=(M,N,P) or f:R3→R3 (vector fields in space)
