Externally Tangent Circles
Description
Two circles of non-equal radius, both in the same plane, are said to be tangent to each other if they meet at only one point.
Two circles are externally tangent if the distance between their centres is equal to the sum of their radii.
Variables

y2 | Y-coordinate of the center of other circle (dimensionless) |
r1 | Radius of one circle (dimensionless) |
r2 | Radius of other circle (dimensionless) |
