Adobe Acrobat XI Pro was used to OCR the text and also for the merging and conversion to the final presentation PDF-format.The systems of orthogonal polynomials mainly used in practice are derived from a common general formula, which is established by the principle of least squares, utilizing results from the Finite Calculus. A simplified method of utilizing the Aitken-Chebyshev polynomials, by means of an extensive set of appended standard tables, is presented.en© 1943 ARC - Onderstepoort and Faculty of Veterinary Science, University of Pretoria (original). © 2017 University of Pretoria.
