The Greeks focused on the calculation of chords, while mathematicians in India created the earliestknown tables of values for trigonometric ratios (also called trigonometric functions) such as sine. Sine calculator. side side angle (SSA) method and only use the law of sines to complete calculations for other unknowns. If you want to calculate the length of a side, you need to use the version of the sine rule where the lengths are the numerators: a/Sine (A) = b/Sine (B) = c/Sine (C) You will only ever need two parts of the sine rule formula, not all three. These angles add up to 180° for every triangle, independent of the type of triangle. For this triangle, (leg) 2 + (leg) 2 = (hypotenuse) 2 becomes f 2 + k 2 = r 2. You may adjust the accuracy of your results. In order to calculate sin(x) on the calculator: Enter the input angle. The Sine Calculator has a single text field and two controls which perform different functions. Trigonometry Calculator  Right Triangles: Enter all known variables (sides a, b and c; angles A and B) into the text boxes. The classic trigonometry problem is to specify three of these six characteristics and find the other three.

Law of Sines. If a, b and c are the lengths of the legs of a triangle opposite to the angles A, B and C respectively; then the law of sines states: Triangle semiperimeter, s = 0.5 * (a + b + c), Triangle area, K = √[ s*(sa)*(sb)*(sc)], Radius of inscribed circle in the triangle, r = √[ (sa)*(sb)*(sc) / s ], Radius of circumscribed circle around triangle, R = (abc) / (4K). 1  Use Sine Law Calculator When 2 Angles and one Opposite Side are Given (AAS case) Enter the 2 angles A and B (in DEGREES) and side a (opposite angle A) as positive real numbers and press "Calculate and Solve Triangle". You can select the angle and side you need to calculate and enter the other needed values. Each triangle has six main characteristics: three sides a, b, c, and three angles (α, β, γ). a = side a P = perimeter Some calculation choices are redundant but are included anyway for exact letter designations.
