Statement:The law of cosine states that the square of any one side of atriangleis equal to the difference between thesumof squares of the other two sides and double the product of other sides and cosine angle included between them. Let a, b, and c be the lengths of the three sides of...

For any triangle ... a, b and c are sides. C is the angle opposite side c. the Law of Cosines (also called the Cosine Rule) says:
γ = cos-1[a² + b² – c ² / 2ab] By using the inverse cosine of the right side of the equation, you can find the corresponding angle. The resulting angle will be in radians, but you can convert it to degrees using our radians to degrees converter. This...
What is the law of cosines? The law of cosines, which is the same as the Cosine Rule, is a formula to determine the measure of a missing angle or a missing side, provided that some information is given. Consider Figure 1, where a triangle is displayed. The law of cosines equation app...
Law of Cosines Calculator Description The law of cosines , otherwise known as the cosine formula or cosine rule, gives a formula that relates the lengths of the sides of a triangle to the cosine of one of its angles. where is the angle between the sides.
When to Use the Law of Cosines Law of Cosines Examples Cosine Practice Problems Lesson Summary Frequently Asked Questions How do you find an angle using Law of Cosines? Start with the cosine formula. Then plug in all the given information about the sides of the triangle. Carry out the oper...
Componente Curricular::Ensino Médio::MatemáticaThe Law of Cosines relates the three side lengths of a triangle with the cosine of one of its angles. If this angle, call it A, is formed by sides β and γ and opposite side α, then the law of cosines states that α² = β² +...
Does this explanation get you thinking about what cosine represents? About when it should be positive, negative, or zero? Appendix: Another Way to Remember Imagine sides A and B are pointing in the same direction along the horizontal number line. This means c=a+b and the Law of Cosines ...
