1. Give parametric equations x(t), y(t), and bounds for t that produce a line segment from (2,5) to (1,7).
 
 

2. Give parametric equations x(t), y(t), and bounds for t that produce the left half of a circle (centered at the origin) of radius 6 traversed counterclockwise.
 
 

3. Plot the vector field F(x,y) =yi + j for the points (0,0), (2,1), (0,2), (1,-1), and (-1,-2) indicated on the coordinate system below.
