What relationship do the ratios of sin x and cos y share? the ratios are opposites?
Answer :
The sine of the measure of an angle in a right triangle, is the ratio of the opposite side of that angle, to the hypotenuse.
The cosine of the measure of an angle in a right triangle, is the ratio of the adjacent side of that angle, to the hypotenuse.
According to these, we have:
and
Thus, the ratios of both are identical
