Law of sines calc:
Input interpretation |
---|
law of sines |
Alternate names |
sine law | sines law |
Basic definition |
For general triangles, a formula relating the ratios of sines of angles to the opposite side lengths. |
Detailed definition |
Let a, b, and c be the lengths of the legs of a triangle opposite angles A, B, and C. Then the law of sines states that a/(sinA) = b/(sinB) = c/(sinC) = 2R, where R is the radius of the circumcircle. |
