WebJan 16, 2024 · That means that a right triangle can be formed with any two angles that add to π 2 —in other words, any two complementary angles. So we may state a cofunction identity: If any two angles are complementary, the sine of one is the cosine of the other, and vice versa. This identity is illustrated in Figure 2.3.10. WebSine is a trigonometric ratio comparing two sides of a right triangle. Sine is usually shortened to sin but is pronounced sine. This function can be used to determine the length of a side of a triangle when given at least one side of the triangle and one of the acute angles. Quick Review: the three main trig ratios are sine, cosine and tangent.
