huh? really?
you can't just look it up in your table?
If not, what is the problem?
There must be more to this story. Is it in degrees, or radians?

Perhaps the tables are from a text from the 80's and have only whole number degrees.
So you need some type of interpolation
from "old" tables:
sin 27° = .4540
sin 27.6° = x
sin 28° = .4695
(x-.4540)/(.4695-.4540) = (27.6-27)/(28-27)
x-.4540 = (.6)/1 * .0155
x = .4540 + .0093 = .4633
It wasn't too much later after that when we advanced to the slide rule
