Plot harmonic motion of x in time, as described by the following equation x(t)=Acos(wt + phi) In this equation, A is the amplitude of the motion, w is the angular frequency, and phi is the phase shift, all of which are defined by the user.
and then when another harmonic motion in the y direction is also present: y(t)= Bcos(2wt - phi)

Where is the code for this question?

Not only is the answer sitting there plain as day, there were literally two duplicate copies of it.

N = 200;
phi = pi/4;
A = 1;
B = 1;
t0 = -2;
tf = 2;
t = t0:(tf-t0)/(N-1):tf;
w = pi;
x = A*cos(w*t+phi);
y = B*cos(2*w*t-phi);
plot(t,x,'linewidth',3,'color','r')
grid
hold on
plot(t,y,'linewidth',3,'color','b')
a = title('Harmonic motion of phase \phi = \pi/4');
set(a,'fontsize',14);
a = ylabel('y(t), x(t)');
set(a,'Fontsize',14);
a = xlabel('t [-2 2]');
set(a,'Fontsize',14);
legend('x(t)', 'y(t)')
