106. (Contd.)

Figures _A _ and _B_ are sets of coordinate lines.

Figure _A_ shows the four quadrants and a rotating vector.

Figure _B_ shows an X axis marked off in degrees.

above the X axis. This height represents the magnitude of the y vector.

For each 15 rotation of the resultant vector in a counterclockwise direction, plot a point

above or below the corresponding degrees on the X axis of figure _B_ .

The first four points have been plotted for you.

You are to plot the other points through one complete cycle (0 through 360). You are

then to draw a line, connecting the plotted points, to form a sine curve.
