sine and cosine rules

sine and cosine rules The Sine Rule is used in the following cases CASE 1 Given two angles and one side AAS or ASA CASE 2 Given two sides and a non included angle SSA The Sine Rule states that the sides of a triangle are proportional to the sines of the opposite angles In symbols Case 2 SSA or The Ambiguous Case

The sine rule can be used to find an angle from 3 sides and an angle or a side from 3 angles and a side The cosine rule can find a side from 2 sides and the included angle or an angle Laws of sines and cosines review article Khan Academy Google Classroom Review the law of sines and the law of cosines and use them to solve problems with any triangle Law of sines a sin b sin c sin Law of cosines c 2 a 2 b 2 2 a b cos Want to learn more about the law of sines Check out this video

Sine Cosine and Tangent often shortened to sin cos and tan are each a ratio of sides of a right angled triangle For a given angle each ratio stays the same no matter how big or small the triangle is To calculate them Divide the length of one side by another side Example What is the sine of 35 When for real values and sine and cosine can be expressed in terms of real sines cosines and hyperbolic functions as sin z sin x cosh y i cos x sinh y cos z cos x cosh y i sin x sinh y displaystyle begin aligned sin z sin x cosh y i cos x sinh y 5pt cos z cos x cosh y i sin x
