circle_circle
Intersection of the circle C1 and radius R1 and the circle with center C2 and radius R2

Write the values in the boxes.  Then press    -  Clear all:   Clear C1/C2:

---

C1x = C1y =     R1 =

C2x = C2y =     R2 =

---

P =  , 

Q =  , 

dist. C1-C2 =    

[if you get  NAN = "not a number"  there is no solution]

If you have to put a coefficient using some function symbol (1/5,π,√2,...), put it in a numerical form (calcolatrice)
