Question

. Show that the sphere x2 + y² + z 2 + 2ux +2vy + 2wz + d = 0)
cuts the second sphere x2 + y2 + z2 + 2u'x +2v'y + 2w'z + d' =0)
in a great circle, if 2 (uu' + w' + ww') = 2x2 + d + d'.​

Answer 1

Answer:

don't know don't know don't know don't know don't know

Answer 2

Answer:

Hence proved

2(uu1+vv1+ww1)=2r1²+d+d1.

Step-by-step explanation:

I used (u1,v1,w1) instead of (u',v',w').

Hope it helps.
