Activity 13.2.2.
For each curve below, find a parametrization of the curve. Ensure that each curve’s orientation matches the one specified.
(a)
The line segment in
\(\R^3\) from
\((0,1,-2)\) to
\((3,-1,2)\text{.}\)
(b)
The line segment in
\(\R^3\) from
\((3,-1,2)\) to
\((0,1,-2)\text{.}\)
(c)
The circle of radius
\(3\) (in
\(\R^2\)) centered at the origin, beginning at the point
\((0,-3)\) and proceeding clockwise around the circle.
(d)
In
\(\R^2\text{,}\) the portion of the parabola
\(y^2 = x\) from the point
\((4,2)\) to the point
\((1,-1)\text{.}\)
