The sphere through four given points. Lecture 2.

Analytical Solid Geometry: The Sphere: To find the equation of the sphere passing through four given points. In this lecture a problem of this type is solved. A problem having some other conditions is given for practice. Correction: In the solution of the first problem the correct values of v and w are: v = -25/14 and w = -11/14. Then the equation of the sphere is 7(x^2+y^2+z^2)-15x-25y-11z =0.
