What is tangent plane to a sphere?
What is tangent plane to a sphere? Also we know that for a plane (having direction ratios as a, b and c) whose equation is given by ax+by+cz+d=0 to be a tangent plane to any sphere (x−x1)2+(y−y1)2+(z−z1)2=R2 →(3) where the centre of the sphere is C(x1,y1,z1) and radius as R, Read more…
