Select angle type of degrees (°) or radians (rad) in the combo box. Weisstein, Eric W. "Law of Sines" From Before getting stuck into the functions, it helps to give a nameto each side of a right triangle: \( A = \sin^{-1} \left[ \dfrac{a \sin B}{b} \right]\), \( \dfrac{a}{\sin A} = \dfrac{b}{\sin B} = \dfrac{c}{\sin C} \), \( A = \sin^{-1} \left[ \dfrac{a \sin B}{b} \right] \), \( A = \sin^{-1} \left[ \dfrac{a \sin C}{c} \right] \), \( B = \sin^{-1} \left[ \dfrac{b \sin A}{a} \right] \), \( B = \sin^{-1} \left[ \dfrac{b \sin C}{c} \right] \), \( C = \sin^{-1} \left[ \dfrac{c \sin A}{a} \right] \), \( C = \sin^{-1} \left[ \dfrac{c \sin B}{b} \right] \), CRC Standard Mathematical Tables and Formulae, 31st Edition. Each triangle has six main characteristics: three sides a, b, c, and three angles (α, β, γ). Law of Sines. It was purposely designed to deliver accurate results depending on the values entered in the text fields. Trigonometry Calculator: A New Era for the Science of Triangles. A = angle A B = angle B C = angle C a = side a b = side b c = side c P = perimeter s = semi-perimeter K = area r = radius of inscribed circle R = radius of circumscribed circle Trigonometric functions. s = semi-perimeter Plug in what you know to get f 2 + 7 2 = 14 2. *Length units are for your reference-only since the value of the resulting lengths will always be the same no matter what the units are. You may adjust the accuracy of your results. The interior angles of a triangle always add up to 180° while the exterior angles of a triangle are equal to the sum of the two interior angles that are not adjacent to it. For this triangle, (leg) 2 + (leg) 2 = (hypotenuse) 2 becomes f 2 + k 2 = r 2. How does this law of sines calculator work? Sine and cosine law calculator This calculator uses the Law of Sines : $~~ \frac{\sin\alpha}{a} = \frac{\cos\beta}{b} = \frac{cos\gamma}{c}~~$ and the Law of Cosines : $ ~~ c^2 = a^2 + b^2 - 2ab \cos\gamma ~~ $ to solve oblique triangle i.e. It can also provide the calculation steps and how the right triangle looks.
