Law Of Cosines Calculator

Welcome to our comprehensive guide on solving triangles using the Law of Cosines with the Law of Cosines Calculator. The Law of Cosines is a fundamental trigonometric formula used to find missing sides and angles in non-right triangles. In this article, we’ll explore the concept of the Law of Cosines, its significance, and demonstrate how to use our calculator to solve triangles effortlessly.

Understanding the Law Of Cosines Calculator

In trigonometry, the Law of Cosines relates the lengths of the sides of a triangle to the cosine of one of its angles. For a triangle with sides a, b, and c and angles A, B, and C, the Law of Cosines states:

c2=a2+b2−2ab⋅cos(C)

a2=b2+c2−2bc⋅cos(A)

b2=a2+c2−2ac⋅cos(B)

These equations allow us to find the length of any side of a triangle when the lengths of the other two sides and the included angle are known.
