1. ## graph r(t)=ti+tj+t^3 k

could somebody give me some advise to graph r(t)=ti+tj+t^3 k?i do not own a graph calculator,so i need the way to solution.Thank you very much.

In you vector equation
$x=t$
$y=t$
$z=t^3$

Becuase of this x=y for all values of t.

so the space curve will be in the plane y=x.

now the z component will trace out a cubic in the plane y=x.

I hope this helps.
