Web18 nov. 2024 · For context, I am a high school math teacher and we were studying Law of Sines and Cosines in our Honors Precalculus course. One of my students asked about Law of Tangents, and discovered that both it and a Law of Cotangents exist, but we were unable to find Laws of Secants and Cosecants. algebra-precalculus. WebThe Law of Cosines for a right triangle (angle A is a right angle) Let’s consider the remaining case: one of the angles (angle A) in the considered triangle BAC is right. According to the definition of the cosine, the cosine of angle is the ratio of the adjacent leg to the hypotenuse. Therefore, from the right triangle BAC we have: From here:
