7) Click EXE again to update the value of f(x) and obtain the 2nd iterate: 0.5452392119
8) recall f() and insert ans, so you get f(ans) and press OK or EXE several times
the final result is 0,567143xxxx

That's a huge improvement, requiring only repeated EXE presses to obtain the next iterate! Thank you for suggesting it!
