To store the function in y1, press the diamond key then press F1.  Now fill
in the function using x as the variable.  Then go back to the Home screen
and press 2nd MATH (the 5 key) then Alpha a, Enter.  This will put the
derivative function on the home screen.  Now type in "y1(x),x)"  without the
quotes and press Enter.  The derivative will be calculated.  See page 64 of
your manual for details.
