Given that n is positive, it could be a positive fraction, 1, or a fraction of whole number greater than 1. If n = 1, then case I is not true since n2 = 1 Likewise in II if n = 1, n - n2 = 0, and the statement is not true. In III, if n = ½, then 2n - ...
The sine of an angle is equal to the cosine of the angle's complement. This relationship can be expressed by the equation sin x°=(cos)(90°-x°). Therefore, if sin x°=a, then (cos)(90°-x°) must also be equal to a.Choices A and B are incorrect and may result from ...
