WebMay 9, 2024 · Figure 5.4.9: The sine of π 3 equals the cosine of π 6 and vice versa. This result should not be surprising because, as we see from Figure 5.4.9, the side opposite the angle of π 3 is also the side adjacent to π 6, so sin( π 3) and cos( π 6) are exactly the same ratio of the same two sides, √3s and 2s. One of the beauties of these trigonometric functions is that you can find the measure of an acute angle of a right triangle if you know two of the sides of the triangle.
