How do you find the area between several functions on ti-89?

Question

I found the area in between the functions y=e^x, Ln(X), the segment joining pts(0,1) and (1,0) and the line segment joining (1,e) and (e,1) by hand but I want to check my answer on the ti 89. Thank Your for your help.

If that doesn't work look through the list of other calculus programs for one that might do what you want.
