Is there a nonzero rational number q such that sin(q) is rational (radian measure)?
How about a transcendental number with transcendental sine?
(In reply to
How many digits? by Erik O.)
It seems to me that what is meant in the problem is that the rational
numbers are to be exact, so they are perhaps best represented as ratios
of whole numbers rather than as decimals.
