Larger stack size

[Peet]

on the HP41 you can do it like on paper (needs only 3 stack level):

2 ENTER ,2+ 2 x<>y y^x 2+ 2* 2 ENTER 2+ - 2* 2* 2* 2* 2/ 2/
result: 36,75834735

there are many more keystrokes and sources of error in the AOS input and worst, you don't even see if you made a mistake.

I never had an AOS Calculator an I am curious, how do you solve this with AOS?

(((2x(2x(2x(2xSIN(2x(2+2^(2+.2))-(2+2))))))/2)/2)
