By using appropriate software/programming, sketch the following vector functions:
1) 2cos(2t)i + 2sin(3t)j for t within o to 2pai
2) 16sin^3ti + (13cost - 5cos2t - 2cos3t - cos4t)j for t within 0 to 2pai
pi, not pie or pai or ...
try typing your functions in here.

rather than expressing them as vector components, use parametric equations.
