For e.g I have two curves say, sin(x) and cos(x), using hold on plots both of them in the figure. But then, how can I place one of them on top of another such that when I use Rotate 3-D both of them are visible at some distance from each other(height).

Plot using plot3(). Have a different z value for each curve so that they are separated along the z dimension.
x = linspace(0, 3*pi, 200);
y1 = cos(x);
y2 = sin(x);
z1 = 2*ones(1, length(y1));
z2 = 4*ones(1, length(y1));
plot3(x, y1, z1, 'LineWidth', 2);
hold on;
plot3(x, y2, z2, 'LineWidth', 2);
grid on;

hold on is still the way to go. Matlab will (should) always plot things where you define them. So, if you define sin(x) and cos(x) in the (x,y) plane, this inherently means that z = 0 ( for both of them). If you want to set z too, use plot3(x,y,z) instead of plot(x,y).
