+arc+cos%28+theta+%29+=+0+
This reads " the angle whose cosine = 0 is theta "
The solutions in the interval [0, 2*pi ] are:
+theta+=+pi%2F2+
+theta+=+3%2Api%2F2+

Cos theta -1=0 find all solutions in the interval [0, 2pi)
~~~~~~~~~~~~~~~~~~~~~~~~`

Cos(theta) - 1 = 0   <----->   cos(theta) = 1   <----->   theta= 0 in this interval.

Answer. theta = 0 is the only solution in the given interval.
