WebIn trigonometry, the law of cotangents is a relationship among the lengths of the sides of a triangle and the cotangents of the halves of the three angles. This is also known as the Cot Theorem.. Just as three quantities whose equality is expressed by the law of sines are equal to the diameter of the circumscribed circle of the triangle (or to its reciprocal, depending … Web16 jan. 2024 · US20240068937A1 US17/792,521 US202417792521A US2024068937A1 US 20240068937 A1 US20240068937 A1 US 20240068937A1 US 202417792521 A US202417792521 A US 202417792521A US 2024068937 A1 US2024068937 A1 US 2024068937A1 Authority US United States Prior art keywords variant computer variants …
