Sin and cosine laws
WebbThe Law of Tangents is a statement involving the tangents of two angles in a triangle and the lengths of opposite sides. The Law of Tangents state: a-b/a+b = tan [1/2 (A-B)]/tan [1/2 (A+B)] ( 13 votes) jhou 9 years ago If you search the law of sines on the internet, it'll mostly give you A/sin (a) = B/sin (b) = C/sin (c). WebbThen, the law of cosine states that: a 2 = b 2 + c 2 − 2bc·cosA. As stated above, the law of cosines in trigonometry generalizes the Pythagorean theorem. If you plug 90º for the …
