I have an arc starting at 0,0 (x=0 & y=0) call this "P1". (counter-clockwise)
The raidus is 1329.0000000
The start angle is 68.45736452
The end angle is 90.00000000
The arc-length is 499.69060185
Also from "P1" horizontally back to the left (angle=180.000000), to a vertical 90 degree line from the end-angle of the 1st arc is 488.0000000 long.
This is how I found my starting point (P1) on the 1st arc.
At the start-angle (P1) a vertical line is 28.875000 long. (This length will never change)
Angle = 90.0000000
At the end of this line (call this "P2") is the start of another arc going counter-clockwise.
The radius is 77.15944660 (This radius will never change)
Back to the center-point of the arc is:
The Angle in XY Plane = 277.43909137 (from "P2")
Delta X = 9.99000000
Delta Y = -76.51000000
I need a calculation to find the intersection of these 2 arcs. (in terms a dummy like me can understand)
I hope someone can help!
A sketch would be good.
If you can create one, you can then upload it (click "Post reply" then in the "Image Upload" section, select 1 or more upload slots, find the file using browse and click submit)

Yes, please try to make an image... I tried drawing it myself but I had a hard time understanding what you were trying to say at some points, so I only got as far as the first circular segment/arc.
See if the image comes through...
Windows explorer doesn't show any upload slots for images...
Give/send an email address and I will send it to you.
Upload your image on imageshack.us or something, then take the forum hotlink (1 or 2 - there are two options) and post it here.
EDIT: Wait, just use the MathsIsFun uploader - I think it can upload images.
Is there such a thing?

Where is the image upload link?
Well i'll be darned...
After posting this "quick message", I saw an "edit" link, I edited this message an... up poped an image upload slot.
It's amazing how web site builders overlook the simple things!
Here is the Image!
