shading region

[Tommy]

is it possible to shade in a region between graphs eg. y=e^x, y=e^-x and y=3

[Mark]

Unfortunately this is not possible directly. The nearest you can get is by entering the equations as inequalities. For example if you enter the following inequalities:

y >= e^x
y >= e^-x
y <= 3

the area left unshaded will be the region you are interested in.

Hope this helps.

Thanks for that!
