14.1 SUMMARY . A vector-valued function is a function of the form A sample is shown fort cate with a diagram the position vectors r ( t ) = (x (1 ) . y (1), z(1) > = x(1)i + >(1)j+ z(1)k (10 - DZ + 1 . We often think of f as time and r() as a moving vector whose terminal point traces out a path as a function of time. We refer to r() as a vector
