3. Enter vectors describing the initial path of
the boat, water current, and resultant path
of the boat.
Store these vectors as
i
,
c
, and
r
. Use the
value
a
for the unknown speed of the
current. Use the value
b
for the speed of
the boat.

Vectors are commonly written in either polar
or rectangular form, so it is useful to convert
polar vectors into rectangular form.
4. Define function
p2r
.
Enter:
Define p2r(x)=[x[1,1]*cos(x[1,2]),
x[1,1]*sin(x[1,2])]
