Cos 90 Degrees
Kos (90 degrees W) =?
Our second term in cricket is painful because it sounds like 0 and 0.
In any case, it is sufficient to follow the cosmic extension by lowering the angle.
cos (AB) = (because A * cos B) + (sin A * sin B)
Then, in both cases, the price accepts the second term as p.
The price is
cos (90 ° p) = cos 90 ° cos p + sin 90 ° sin p
If p = 0
Case (900) = (0) (1) + (1) (0) = 00 = 0
If p = 0
cos (90O) = (0) cos O + 1 (sin O) = 0+ sin O = sin O.
Cass (90 degree 0) = 1
If the cosine angle is 90 degrees 0, then 0 can be omitted because 0 is 0 and therefore it becomes easier in cos (90). If we look at the unit circle at 90 degrees and find the cosine (or y-coordinate) of the right point ((0,1)) degrees, we know that cos (90) = 1.
Cass (90 degree O) = sin O.
I don't think 0 is O (z oh) so the answer is Z because cos (90) z. This
