I seem to have a problem with solutions for a sine function. A 60 hz frequency leads to a problem. A frequency of 60 hz leads to an angular frequency of 377 rad/sec.

First, look at 3.77 rad/sec, which leads to a correct answer:
Solve(sin(3.77t),t, [0,10]). Gives, 0, 100 pi/377 for the first two roots

Next, look at 37.7 rad/sec, which leads to a correct answer:
Solve(sin(37.7t),t,[0,1]). Gives, 0, 10 pi/377 for the first two roots

But, for 377 rad/sec, we get an incorrect answer:
Solve(sin(377t),t,[0,0.1]). Gives, 0, 4 pi/377, the correct answer is 0, pi/377.

Any thoughts?

Thanks
