# Math 222 Current Assignment

## Due Friday, February 16

Drawing the curve uses the Maple function *spacecurve*. Increasing the
number of points computed for the picture will make things much smoother;
e.g. add the option *numpoints=200* to the *spacecurve* call.
The plots of speed and acceleration length are two dimensional, so
should be done by the Maple function *plot*.

Remember vectors and curves can be represented as lists (closed brackets) in Maple.

To determine the length of a vector, one can use the function *dotprod*
from the linear algebra package. This requires loading the package
(**with(linalg;**) first of course.

The worksheet **Curves** in **Math 222:Lecture 4** illustrates the use of
the map function to differentiate each entry of a list. This is needed
in determining the velocity and acceleration.
