[EXTRACT FROM A] REPORT ON MATHEMATICAL TABLES.
[From the Report of the British Association for the Advancement of Science, (1873),
pp. 3, 4.]
It was necessary as a preliminary to form a classification of mathematical (numerical)
tables; and the following classification was drawn up by Prof. Cayley and adopted by
the Committee.
A. Auxiliary for non-logarithmic computations.
1. Multiplication.
2. Quarter-squares.
3. Squares, cubes, and higher powers, and reciprocals.
B. Logarithmic and circular.
4. Logarithms (Briggian) and antilogarithms (do.); addition and subtraction
logarithms, &c.
5. Circular functions (sines, cosines, &c.), natural, and lengths of circular arcs.
6. Circular functions (sines, cosines, &c.), logarithmic.
C. Exponential.
7. Hyperbolic logarithms.
8. Do. antilogarithms (e*) and h . 1 tan (45° + \ <£), and hyperbolic sines, cosines,
&c., natural and logarithmic.
D. Algebraic constants.
9. Accurate integer or fractional values. Bernoulli’s Numbers, A n 0 w , &c.
Binomial coefficients.
10. Decimal values auxiliary to the calculation of series.
