Connor Smith is a professor of electrical and computer engineering with expertise in electromagnetics, microsystems, and magnetic materials and devices. The Law of Cosines, also called the Cosine Rule, is a formula that relates the lengths of the sides of a triangle to the cosine of its angles. It is a generalization of the Pythagorean theorem , and you can use it to solve the length of sides or angles for triangles, even if they are not right triangles.

The law of cosines calculator can help you solve a vast number of triangular problems. You will learn what is the law of cosines also known as the cosine rule , the law of cosines formula , and its applications. Scroll down to find out when and how to use the law of cosines, and check out the proofs of this law. Thanks to this triangle calculator, you will be able to find the properties of any arbitrary triangle quickly. But if, somehow, you're wondering what the heck is cosine, better have a look at our cosine calculator. The law of cosines states that, for a triangle with sides and angles denoted with symbols as illustrated above,. The law of cosines alternatively the cosine formula or cosine rule describes the relationship between the lengths of a triangle's sides and the cosine of its angles. It can be applied to all triangles, not only the right triangles. This law generalizes the Pythagorean theorem, as it allows you to calculate the length of one of the sides, given you know the length of both the other sides and the angle between them. The law appeared in Euclid's Element , a mathematical treatise containing definitions, postulates, and geometry theorems. Euclid didn't formulate it in the way we learn it today, as the concept of cosine had not been developed yet. The first explicit equation of the cosine rule was presented by Persian mathematician d'Al-Kashi in the 15th century.
