Consider the parametric equations
x = t cos 39°
y = t sin 39°
a. Make a graph with window -1 (x ( 10, -1 (y ( 10, and 0 ( t ( 10.
b. Describe the graph. What happens if you change the minimum and maximum values of t?
c. Find the measure of the angle between this line and the x-axis. (Trace to a point on the line and find the coordinates.)
