If the origin is moved to the point (/?, /c, /), the axes remainingparallel to the old ones show that the formulas for transformation are X = x + h, y = y + k, z = z + I. 9. If the origin remains unchanged, and the axes are turned co thatthey make these direction angles with the old axes (a^, j8j,… … X = ON, y = MN, z = PM.x = OW, y - MN, z = PM. Now, the projections of OP and ONMT on the rc-axis [old] are equalSimilarly on the other axes. Hence, the above formulae. 10. Find the radius vector with its direction cosines for each of thepoints (2, 4, 6), (3, -2, -1), (1, -2, -3). 284 ANALYTICAL…
