An introduction to mathematics, by A. N. Whitehead.
TRIGONOMETRY 181 centre 0, as do the two circles in fig. 26, then the arcs AP and A1P1 intercepted by the arms of any angle AOP, are also in proportion to their radii. Hence the ratio of the IA /A'/ M \ Ar O A A, Fig. 26. length of the arc AP to the length of the radius OP, that is a is a number which radius OP is quite independent of the length OP, and is the same as the fraction arc 4 P. This fracradius OP1 tion of "arc divided by radius" is the proper theoretical way to measure the magnitude of
