The modify version also used Register 3 in the program, is that OK to use in the
f(x) program with RCL 3 ?

I try both Newton's and Regula Falsi methods on Modern 12C+ and on Official 12C App on Android OS. Both devices run both methods equally fast of about one second.

For Newton's Method I find that the program is shorter is only about 41 lines of code versus 75 lines of the Regula Falsi Method program.

Newton's Method is more cumbersome to input all the necessary data for regular user such as Store Initial Guess, Store tolerance

Regula Falsi Method is very easy to input data, user only put two initial guesses then R/S that's all.

I like to know how long it take to compute with the older version of the HP-12C For comparison Newton's Method run slow on HP-11C but with Regula Falsi this method run faster and very reliable it can take almost any equation with ease.
