% (ch2p12:Functions of time, can be easily plotted
% using MATLABs plot(X,Y,S), where X is the
% independent variable, Y is the dependent variable,
% and S is a character string describing the plots
% color, marker, and line characteristic. Type HELP PLOT
% in the Command Window to see a list of choices for S.
% Multiple plots also can be obtained using
% plot(X1,Y1,S1,X2,Y2,S2,X3,Y3,S3,. . .).
% In the following example we plot on the same graph
% sin(5t) in red and cos(5t) in green for
% t = 0 to 10 seconds in 0.01 second increments.
% Time is specified as follows:t = start:increment:final.
'(ch2p12)' % Display label.
t=0:0.01:10; % Specify time range and increment.
f1=cos(5*t); % Specify f1 to be cos(5t).
f2=sin(5*t); % Specify f2 to be sin(5t)
plot(t,f1,'r',t,f2,'g') % Plot f1 in red and f2 in green.
