cos a 2 formula The half angle formula of cos is cos A 2 1 cos A 2 We have another half angle formula of cos in terms of semiperimeter If a b and c are the sides of a triangle and A B and C are their corresponding opposite angles then cos A 2 s s a bc
Solving for cos 2 we obtain cos alpha 2 sqrt 1 cos alpha 2 As before the sign we need depends on the quadrant If 2 is in the first or fourth quadrants the formula uses the positive case cos alpha 2 sqrt 1 cos alpha 2 If 2 is in the second or third quadrants the formula uses the negative case cos alpha 2 Trigonometric Ratios of Angle A 2 in Terms of cos A We will learn about the trigonometric ratios of angle A 2 in terms of cos A How to express sin A 2 cos A 2 and tan A 2 in terms of cos A i For all values of the angle A we know that cos A 2 cos 2 A 2 1 2 cos 2 A 2 1 cos A

The Law of Cosines For any triangle a b and c are sides C is the angle opposite side c the Law of Cosines also called the Cosine Rule says c 2 a 2 b 2 2ab cos C It helps us solve some triangles Let s see how to use it Example How long is side c We know angle C 37 and sides a 8 and b 11 The law of cosines alternatively the cosine formula or cosine rule describes the relationship between the lengths of a triangle s sides and the cosine of its angles It can be applied to all triangles not only the right triangles

To find cos B 2 start with a different piece of the cos 2A formula from equation 59 cos 2A 2 cos A 1 As before put B 2 cos B 2 cos B 2 1 Rearrange and solve for cos B 2 cos B 2 1 cos B 2 cos B 2 1 cos B 2 You have to pick the correct sign for cos B 2 depending on the value of B 2 just as The cosine formulas are formulas of the cosine function in trigonometry The cosine function which is usually referred to as cos is one of the 6 trigonometric functions which is the ratio of the adjacent side to the hypotenuse
