You just beat me to it, but here's my sequence for 34 digits:

Code:


round(asin(round(acos(round(atan(round(tan(round(cos(round(sin(round(round(9*rou​nd(pi*10^33))/18)*10^-34)*10^34)*10^-34)*10^34)*10^-34)*10^34)*10^-34)*10^34)*10^-34)*10^34)*10^-34)*10^34)*10^-34

It's incomplete because the free version won't allow me to make it any longer, but all it's missing is the / pi * 180:

Typing in the previous result:

Code:


round(round((0.1570796326794896619231321691639748/round(pi*10^33)*10^33)*10^35)*10^-35 * 180 * 10^33)*10^-33

Gives the correct answer for 34 digits:

8.999999999999999999999999999999980

This is exactly what I get with newRPL (previously I reported 79 with the /pi*180 reversed, which is also correct).

This can be used for any digits, changing the 34/33/35 accordingly for prec/(prec-1)/(prec+1).
