106. Solution. This is the way the completed sine wave should look:
No magnitude is assigned to the y vector of the graph you plotted. However, if the "Y"
axis is marked off in units, representing volts or amperes, the magnitude (value) of y
can be found at any point.
Compare the circled positions 1, 2, 3 of the rotating vector with corresponding positions
on the sine wave. You would get these same values by using trigonometry to solve for
