Is there any way to force a Ti-89 to output a decimal approximation as opposed to outputting a fraction? I’ve looked through all the menus, but I can’t find anythign that would help me do this.

Also, is there any way to put cscx, secx, or cotx into the main screen other than having to use 1/trig equivalent?

Thanks for the help.
