so here's the code:
t=0:pi/120:2*pi;
x=5+3*cos(t);
y=7+3*sin(t);
plot(x,y)
axis equal
the only confusing part is t or theta, can somebody explain it to me how it works? Thanks!

take a look at t (remove the semicolon or look at it in the workspace):
t=0:pi/120:2*pi
And to visually look at it:
plot(t)
