## An elementary treatise on solid geometry by Smith, Charles, 1844-1916

By Smith, Charles, 1844-1916

This publication used to be initially released sooner than 1923, and represents a duplicate of an immense old paintings, holding an analogous structure because the unique paintings. whereas a few publishers have opted to follow OCR (optical personality reputation) expertise to the method, we think this ends up in sub-optimal effects (frequent typographical mistakes, unusual characters and complicated formatting) and doesn't safely protect the historic personality of the unique artifact. We think this paintings is culturally very important in its unique archival shape. whereas we try to thoroughly fresh and digitally increase the unique paintings, there are sometimes cases the place imperfections equivalent to blurred or lacking pages, negative photographs or errant marks could have been brought as a result of both the standard of the unique paintings or the scanning approach itself. regardless of those occasional imperfections, we've introduced it again into print as a part of our ongoing worldwide publication renovation dedication, delivering consumers with entry to the very best historic reprints. We have fun with your knowing of those occasional imperfections, and truly desire you take pleasure in seeing the ebook in a layout as shut as attainable to that meant via the unique writer.

Are x = 0, y = 0, z= Find the co-ordinates of the centre of the sphere in 25. scribed in the tetrahedron formed by the planes whose equations =- a. are y + z - 0, z + x - 0, x + y = 0, and x + y + z CHAPTER III. SURFACES OF THE SECOND DEGREE. The most general equation of the second degree, viz. 50. 2 ax* + + cz* + 2fyz + 2^,7? + 2htvy -f 2w + 2vy + 2wz + d = 0, contains ten constants. But, since we may multiply or divide the equation by any constant quantity without altering the relation between as, y, and z which it indicates, there are really only nine constants which are fixed for any particular surface, viz.
