What is Descartes' purpose in exercising this method?, Why can't Descartes be certain about beliefs he acquires through the evidence of the senses?, Why can't Descartes be certain about mathematical beliefs like the belief that 2+2=4? and more.
Descartes' circle theorem (a.k.a. the kissing circle theorem) provides a quadratic equation satisfied by the radii of four mutually tangent circles. By solving this equation, one can determine the possible values for the radius of a fourth circle tangent to three given, mutually tangent circles.
24 Ιαν 2022 · Theorem (Descartes circle theorem, 1643) If b 1;b 2;b 3;b 4 are bends of four mutually tangent circles, then (b 1 + b 2 + b 3 + b 4) 2 = 2(b2 1 + b 2 2 + b 2 3 + b 2 4): Example 0 0 1 1 b 1 = b 2 = 0, b 3 = b 4 = 1 (0 + 0 + 1 + 1)2 = 22 = 4 2(02 + 02 + 12 + 12) = 2(2) = 4 Edna Jones The Descartes circle theorem
We present a short proof of the Descartes circle theorem on the “curvature-centers” of four mutually tangent circles. Key to the proof is associating an octahedral configuration of spheres...
