(standard deviation is WIP) (cosine rule for the angle has some bugs, please wait for adjustments) Quadratic formula: substitutes and solves for ax²+bx+c=0. For x with no coefficient just write 1. Negative numbers also work Cosine rule for the angle in the triangle: input lengths a, b and c (length a must be the length of the side of the triangle opposite the wanted angle, while b and c are the 2 sides "cuddling" the wanted angle. b and c are interchangeable) and it will give you the size of the enclosed angle Cosine rule for length a : Input b and c (the other 2 lines of the triangle that aren't a, in any order) and the angle A (the angle opposite to the missing length a) and you will be given the missing length of a
