It follows from the cyclical symmetry of the cosine rule.
To apply the law of cosines to find the measure of an interior angle in a triangle, you need to know the lengths of all three sides of the triangle. Specifically, if you have sides ( a ), ( b ), and ( c ), you can use the formula ( c^2 = a^2 + b^2 - 2ab \cos(C) ) to solve for the angle ( C ). Thus, knowing the side lengths is sufficient to determine the interior angle.
a2 = b2 + c2 - 2bc cos(alpha) b2 = a2 + c2 - 2ac cos(beta) c2 = a2 + b2 - 2ab cos(gamma) There are all three formulas. Do not forget to use, arc-cos, when finding angles.
It helps, in this type of problem, to convert all trigonometric functions to sines and cosines. As a reminder, tan(x) = sin(x) / cos(x).
If you want to simplify that, it usually helps to express all the trigonometric functions in terms of sines and cosines.

No, the direct cosines of a vector are unique only up to a sign change. This means that if a set of direct cosines uniquely defines a vector, a set of direct cosines with opposite signs for all components would define the same vector.
No, it applies to all triangles.
No, it applies to all triangles.

Cosine Rule: a2 = b2+c2-2bc*cos A is applicable to all triangles
There is none that is more correct because they are all correct.
