Intersection of two circles
Intersection of two circles
(OP)
Hi,
I have two circles with centres (xo,yo) and (x1,y1) respectively. The two circles have radius R1 and R2. The circles are already plotted with help of a series of cumulative small angles (theta) and radius in excel. The two circles intersect at (xi,yi) and (xf,yf) which I have already found as well using mathematical equations.
I have a list of x,y co-ordinates of both the circles which is used to construct the circles. I want a list of x,y co-ordinates of both circles together ignoring the intersection portions between them, so that I can plot the perimeter portion of the circles (peanut shape in this).
Thank you in advance.

I am actually a primitive user of excel and my apologies if it sounds too unprofessional.
With the use of scatter plot, the 2 circles with intersection has been drawn, but I do not want the chart to display the intersection arcs. Without manually removing the points in the arc, can the co-ordinates forming the perimeter "peanut shape" be listed and plotted in graph.
Thank you.
