1 Define 50 points between -3π and 3π and compute their sines and cosines:

x = linspace(-3*pi,3* pi,50);

ys = sin(x);

yc = cos(x);

2 Using the plotting tools, create a graph of ys = sin(x):

3 In the Figure Palette, alternate-click to sele ct x and ys in the Variable pane.

4 Right-click either selected variable and choose plot(x, ys) from the context
