Thank you for the reply.

Chapter 12 of the user manual refers to partial derivatives and multiple integrals, so i assume you meant chapter 12 of the user guide. I have already gone over that chapter and it mostly deals with writing equations directly in the "Y=" window or the "2D/3D" window. The only other input method i could find in that chapter is by using the "Choose" menu in the "Y=" window, but that does not work with equations on the stack or with algebraic objects stored in a variable. It only works with defined equations.

So the question remains. If i have "2X^3" on the stack, can i not input it in either the "Y=" or the "2D/3D" windows? Is the only way to do that by defining it as an equation?

Thank you.
