== The Wolfram approach ==
The task currently references https://mathworld.wolfram.com/Circle-LineIntersection.html which (for now, at least) seems to be incorrect.
Consider, for example, a circle of radius 1 at the origin and a line extending through the origin and the point x=1, y=1. Here, we expect intersections at x and y equal to the square root of 2 and the negative of the square root of 2. Ignoring the negative x and y results for simplicity, and working through the wolfram approach:
I'd like to believe that I'm wrong here -- past experience suggests I make mistakes far more often than anything in Wolfram. But I keep going over this and not seeing where I went wrong. --[[User:Rdm|Rdm]] ([[User talk:Rdm|talk]]) 12:59, 21 October 2022 (UTC)

Error by vb.net
i try to use the vb.net-code but in following constellation is a error
center=10,10
radius=5
line from 5,0 to 5,20
there is no intersection - but it is a point of tangent.
regards Jan
It seems the task author did not include test examples where there is a tangent. --Wherrera (talk) 18:42, 20 October 2022 (UTC)
