If
B
is
the sine of an angle, then OoB yields the cosine of the same angle, and con-
versely,
if
B
is
the cosine, OoB yields the sine. Suppose you wanted the sine of
30
0
,
which
is
equivalent
to
pi
divided by 6:

If
one argument
is
a scalar or a single-element array, the shape of the result
is
the
same
as
that
of
the
other argument. The single element
is
applied
to
every element
of the multielement array:
