I need this for my homework and I managed to do it but the end result wasn't that smooth. Can somebody give me a simple, short code that gets the job done?

hi, correct the word 'ecuations' for future searching. Parametric method is the easiest one :
t=0:0.1:2*pi;
x=cos(t);
y=sin(t);
plot(x,y);

Code examples are in the FAQ: http://matlab.wikia.com/wiki/FAQ#How_do_I_create_a_circle.3F Increase the number of samples if you want a smoother circle.
