TIB: 85 to 89



I have an 85, and want to put a program on my friends 89.
It is just:
 
:(tan Ans)^-1
 
It takes the last answer, and gets the Cotangent of it.  The calc stores this into Ans and displays it on it's own.  I could get it to do this with the 89.  I tried getting an argument as a, applying the cotangent, and then displaying a, but it gave:
 
  1
-------
tan a
 
with a as the argument.  I want the answer to be a decimal.  How do I write this?
