Hello, I am trying to plot the two functions on the same graph and am unable to label both y-axis. Could someone please tell me what I am doing wrong?
t = 0:20;
y1 = (100*sin(pi/4).*t)-(.5*9.8*t.^2);
y2 = 100*sin(pi/4)-9.8.*t;
a = plotyy(t,y1,t,y2);
title('Problem 5.26')
xlabel('time, sec')
ylabel('Position')
ylabel(a(2),'V(t) Vertical Direction')

Nevermind. I ran it again and it worked. Today just isn't my day.
