a and b are whole positive integers, which makes the following identity true. What are the values of a and b? Thanks.
Pi/4 =8arctan(1/10) - arctan(a/b)
0.7853981634...... =0.79734921992... - arctan(a/b)
arctan(a/b) =0.79734921992 - 0.7853981634......
arctan(a/b) =0.0119510565318..........
Using "continued fraction" method:
a = 1,758,718
b=147,153,121
The Guest made a copying error:
a =1,758,719.
