How Were Those Tables Computed?



Dear All:

Before the computer/calculator age, people used trigonometric,
logarithmic tables. For instance, to find out sin(38.52 deg)=?, you had
to use such a table. There were of courses tables of many other
functions. And there were slide rules to use, but the precision was
low. The logarithmic table, on the other hand, could provide 7 digits
after the decimal points.

Now the questions: (1) What formulas were used for the computation of
the values in those tables? (2) Were the computation done manually by
some hard-working mathematicians? Or by some adding machine?
