i(t)=6cos((2*pi*t)-15)
And
v(t)=12sin((2*pi*t)-45))
plot on same graph, should include approx 2 full cycles.

13 minutes after your post here, he actually edited his question here to change it to essentially this question. Even if teachers don't check (which they might indeed not do for easier questions), the rest of my argument still stands.

There are three ways:
1)
plot(t, i(t))
hold on
plot(t, v(t))
hold off
2)
plot(t, i(t), t, v(t))
3)
plot(t, [i(t(:)), v(t(:))])
Passing t(:) to the functions should cause them to return column vectors. You then use [,] to put the two column vectors into an n x 2 matrix. MATLAB will treat each column as an independent line to be plotted.
