Another way to calculate the exterior angle of a triangle is to subtract the angle of the vertex of interest from 180°. Area = (1 / 2) b c sin(A) = (1 / 2) c a sin(B) = (1 / 2) a b sin(C) How to use the calculator Here we assume that we are given sides a and b and the angle between them C. Enter sides a and b and angle C in degrees as positive real numbers and press "enter". The sine law for the above triangle is written as a / sin(A) = b / sin(B) = c / sin(C) and is used to solve triangle problems. 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. A = angle A Trigonometric functions.

(Angle "A" is the angle opposite side "a". c = side c b = side b © 2006 -2021CalculatorSoup® Such an angle is called a right angle. To calculate any angle, A, B or C, say B, enter the opposite side b then another angle-side pair such as A and a or C and c. The performed calculations follow the 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 sin A = opposite / hypotenuse = a / c. cos A = adjacent / hypotenuse = b / c. tan A = opposite / adjacent = a / b. csc A = hypotenuse / opposite = c / a. sec A = hypotenuse / adjacent = c / b. cot A = adjacent / opposite = b / a.

Solving for a side in right triangles with trigonometry, How to Add Pi in Trigonometry : Math Conversions, Equations & More, Discover Pi using Algebra, Trigonometry and Calculus. The Greeks focused on the calculation of chords, while mathematicians in India created the earliest-known 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. Math Warehouse's popular online triangle calculator: Enter any valid combination of sides/angles(3 sides, 2 sides and an angle or 2 angle and a 1 side) , and our calculator will do the rest!

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 semi-perimeter, s = 0.5 * (a + b + c), Triangle area, K = √[ s*(s-a)*(s-b)*(s-c)], Radius of inscribed circle in the triangle, r = √[ (s-a)*(s-b)*(s-c) / 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.
