If Pi/4 = 8Arctan(1/10) - Arctan(a/b), what is the fraction a/b? Thanks for help.
Arctan(a/b) =8arctan(1/10) - Pi/4
Arctan(a/b) =0.01195105653184790941190811320429
a/b =tan(0.01195105653184790941190811320429)
a/b =0.01195162554520335317930497716049
Using "continued fraction" method, will convert the above decimal into a proper fraction, a/b:
About half a dozen elementary steps later, we get the proper fraction:
a / b == 1758719 / 147153121
