Real–Number Functions 4-9
To insert a constant:
1. Position your cursor where you want the constant inserted.
2. Press to display the physics constants menu.
3. Press
ÕÖ×Ø (or, you can press to access the next
page, one page at a time) to scroll through the menu until the constant you
want is underlined, then press
to insert the constant.
Note that constants should be referred to by their names rather than their values,
when used in expressions, equations, and programs.
