The problem:
I have a perfectly vertical line with 3 points (A,B,C).
Point A's y value (1st endpoint) = unknown Point B's y value (a point in the line, not necessarily the exact midpoint) = 3.12 Point C's y value (2nd endpoint) = 2.71
I also know that: By - ( (Ay-By) x 1.618 ) = 2.71 AND Ay < 4.38
I need to find the value of endpoint Ay.
Is this problem solvable?
$B-1.618(A-B)=2.71\\B=3.12\\3.12-1.618(A-3.12)=2.71\\1.618A=3.12(2.618)-2.71\\A=\frac{3.12(2.618)-2.71}{1.618}\approx 3.3734$
