3 days ago · The formula is as follows: c = a 2 + b 2 - 2ab cos C. When should the cosine rule be used? You know the lengths of the two sides of a triangle and the included angle. You can then work out the length of the remaining side using the cosine rule. You know the lengths of all the sides but none of the angles.
May 15, 2024 · The formula to find the work done by a particular force on an object is W equals F d cosine theta. W refers to the work done by the force F. In other words, W is telling you the amount of energy that the force F is giving to the object.
