WebSo the law of cosines tells us that C-squared is equal to A-squared, plus B-squared, minus two A B, times the cosine of theta. And just to remind ourselves what the A, B's, and C's … WebThe Law of Cosines. The Law of Cosines states the following: a2 = b2 + c2 -2bc cos (A) Alternative versions look like this: b2 = a2 + c2 -2ac cos (B) c2 = a2 + b2 -2ab cos (C) In the last two formulas, the parts are simply interchanged to make the law easier under our convention of using a, b, c, A, B, and C to label triangles.
