(12C Platinum) Zero of Function

[Gamo]

Thanks to Albert Chan and Dieter for the review.

Dieter program suggestion is more refine and more clear.

--------------------------------------------------------------

I have try my original program for

X^X = Y equation for X^X = 1000

Using this formula: LN(x) * (x) - LN(y)

f(x) equation start line 022 and store 1000 in R5

[RCL] 1 [LN] [x] [RCL] 1 [-] ([RCL] 5 [LN]) [=] [GTO] 008

1000 [STO] 5
First Guess: 6 [R/S] display 65
Second Guess: 4 [R/S] display 4.5555

Fix 9 display 4.555535705

Not bad for when using a good guess.
