Suppose I use a sage function and it's taking too long. Is there a way
to invoke the function with a specified time so that when it exceeds
that given time, it will terminate gracefully without completing the
computation?

Do you have any idea why sage "bool" fails for trig functions with
fractional angles?
Can you suggest any work around?

Any clue why bool(arcsin(x) == 2*arctan(x/(1+sqrt(1-x^2 returns
false where the expressions are mathematically equivalent.
I found that arcsin(x) - 2*arctan(x/(1+sqrt(1-x^2))) is not exactly 0
for all x in [-1,1]. In sage, is there any way to compare expressions
with some numerical precision?
