Determine the measure of A if 0 degrees is less or equal to angle A and if angle A is less or equal to 360 degrees.
Tan A = 0
Answer is somehow supposed to be 0 degrees, 180 degrees, and 360 degrees, but don't know how to get the answer, just really confused.
Sin A = 1

In your text you should have the graphs of the
sine, cosine and tangent curves.
Take a look where the tangent curve cuts the xaxis in the given domain
for the second, look at the sine curve,
when is it at 1, its lowest value.
