Match the vector equations in Exercises $1 - 8$ with the graphs $( a ) - ( h )$ given here.

$$

\mathbf { r } ( t ) = ( 2 \cos t ) \mathbf { i } + ( 2 \sin t ) \mathbf { k } , \quad 0 \leq t \leq \pi

over or is given by to co sign t to assign. See, it was because Auntie Zero to a sci fi. So these are exactly the coordinates for over I, g and K. So now we know that executes two schools, Auntie y zero and Z is to sign t So X squared plus C squared equals to four tons Sewing t squared law school. Isn't he squared? So here's the inclusion export us. This really was for
