 Feb 7 awarded Famous Question Sep 24 awarded Autobiographer Sep 25 awarded Notable Question Mar 11 comment How To Create a Non-Linear Output from a Linear Input? i see, thanks. what would a polynomial example look like? Mar 11 asked How To Create a Non-Linear Output from a Linear Input? Mar 11 accepted How to find center of an arc given start point, end point, radius, and arc direction? Mar 2 awarded Popular Question Mar 22 comment how to tell if an arc is within bounds? henry, i'm still having trouble understanding how to calculate the boundary crossing points and the candidate centers. could you elaborate on the formulas you used? maybe give them to me in abstract form? my algebra is old and crusty, although I'm trying to improve it. Mar 18 comment How to find center of an arc given start point, end point, radius, and arc direction? if i substitute that equation for x, i still end up with an unknown (y), right? IOW, even though i can rearrange the original equations to solve for y, what you're suggesting still leaves a y on the right side. or am i missing something? Mar 17 awarded Supporter Mar 17 awarded Commentator Mar 17 comment How to find center of an arc given start point, end point, radius, and arc direction? hey ross, so how do i rearrange one of these equations to first solve for x, than for y, when they contain both x and y as unknowns? i figure i can rearrange the first one to solve for x like this: x = -x0^2 + (y-y0)^2 = r^2. but that still has the unknown y on the right side.

Mar 17 comment how to tell if an arc is within bounds? thank you so much henry! i also need help finding the center, so posted that in another question Mar 17 asked How to find center of an arc given start point, end point, radius, and arc direction? Mar 16 comment how to tell if an arc is within bounds? does anyone know how henry calculated his values in step #3? Mar 15 comment how to tell if an arc is within bounds? ok, i see what you mean about two centers. in my case, i know which one i'm using as I know which of the two end points is the starting point and i know whether i'm going clockwise or counterclockwise from the start point. Mar 15 comment how to tell if an arc is within bounds? @henry: in #2, what do you mean there could be two centers? at least in how I'm doing this, my radius will always be, at smallest, half the distance between the two points. sometimes larger. but how does having a radius larger than distance/2 result in two arcs? in #3, how are you finding the values (-5,3.93649) and (-5,0.0635)? thanks! Mar 15 comment how to tell if an arc is within bounds? ah, so you're talking about an arc with a different radius, right? is there a formula I can use to detect whether my arc will go out of bounds?
