Sketch the curve with the given vector equation and indicate with the arrow the direction of the curve: a) r(t)=<1+t, 2+t, 3+2t>
Hello, allstar2!
Do they really expect us to sketch a three-dimensional graph?
$\displaystyle \text{Sketch the curve with the vector equation: }\:\vec r(t) \:=\:\langle 1+t,\:2+t,\:3+2t\rangle$
$\displaystyle \text{and indicate with the arrow the direction of the curve.}$
$\displaystyle \text{This is a straight line through the point }(1,2,3)$
. . $\displaystyle \text{with direction vector }\vec v \:=\:\langle 1,1,2\rangle$
