I'm not sure about the TI-85, but the TI-92 can use a function within a
function. Maybe you can create a function called sec or whatever. The
equation would be called from another function.
Try it. I'm not sure if it works, but who knows.
To make the equation, type it in quotes and use the sto> button and
store it into a string. Then use the Catalog to find St>Eq to manke it
into an equation. Like I said, I don't know if it'll work. I don't have
my good TI-85 with me.
