Surface in 2d, or plane region

Hi,

I often need to draw an "elemental region" of the plane, that is a set of the form

a <= x <= b

f(x) <= y <= g(x)

I can do that with the surface command in 3D, but it seems that command is not implemented in the 2D view (why?)

As a workaround I draw it in the xy plane in 3D, but it is annoying that I have to manually "rotate" the xy axis so that they don't look ugly like this

Any idea how can I improve that? Thanks in advance.

Damián.

DId you try IntegralBetween( <Function>, <Function>, <Start x-Value>, <End x-Value> )?

f(x)<=y<=g(x) is wrong syntax try f(x)<=y&&y<=g(x)

it's a slightly different to integral

you mean l1 ?

I think l1 is not an integral. It is something as a "morphing" between f and g.

I meant different results when crossing functions

Interesting variant, thanks.
