matlab freaks?!

[Budweiser [FtS]]

Anyone know Matlab inside out?

I need to plot some basic sinewaves
to demonstrate something for a prac
report. I can do it by hand, but i thought
i'd be smart and show off with matlab!

This is what i need to do (can u believe this
is for an engineering degree?!):

create 2 sinewaves, S1 and S2, with a time
axes of 4pi. S1 has amplitude 1 and S2 has
amplitude 2. S2 leads S1 by 30 degrees (pi/6
rad).

just some help with the matlab code would be great,
or a URL for some matlab tutorials :)

thanx all!
