Sine and Cosine
Figure 3-27 shows the relationship between the sides of a right triangle and the sine and
cosine functions. The sine of an angle is the opposite side of the triangle (y) divided by
the hypotenuse (h). If you know h and y, and want to know the angle (θ), use arcsine
(sin
the angle given x and h, use arccosine (cos
−1
). The cosine of the angle is the adjacent side (x) divided by h. If you want to know
