## Intersection of two Spheres

Given the center and radius of two spheres the program calculates
the center and radius of the intersection circle and the coordinate equation
of the intersection plans.

If a radius of Zero is entered, the equation of the tangential plane is determined.

### Example:

Given the two spheres:
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
K1 : M1(3|3|3) , r1 = 3
K2 : M2(1|1|1) , r2 = 3
Intersection circle:
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
M(2|2|2) , r = 2,4494897
Intersection plane :
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
E : x + y + z = 6
