Draw a straight horizontal line of a known length (say 50). At the right hand end of that line, draw a vertical line of the same length. Join the two ends with a curve so that you end up with a picture that looks like the top left quadrant of a circle.

I need a formula that will identify the vertical distance between the horizontal line and the arc for any location along the horizontal line.

SO, as an example, for the point on the horizontal line that is 10 away from the vert line, I need to be able to get the vertical distance between that point and the arc.

Hope this makes sense.

Thanks
