For angles,sinAa=sinBb=sinCcsinAa=sinBb=sinCc What is the Cosine Rule? To find a side when you know the other two sides and the angle between them use: a2=b2+c2−2bccosAa2=b2+c2−2bccosA To find an angle when you know three sides use: ...
Cosine rule, in trigonometry, is used to find the sides and angles of a triangle. Cosine rule is also called law of cosine. This law says c^2 = a^2 + b^2 − 2ab cos(C). Learn to prove the rule with examples at BYJU’S.

The law of cosine is also known as the cosine rule. This law is useful to find the missing information in any triangle. For example, if you know the lengths of two sides of a triangle and anangleincluded between them, this rule helps to find the third side of the triangle. Let us c...

Let us find the derivative of y = cos-1x. By the definition of arccosine, y = cos-1x can be written as cos y = x. Differentiating this on both sides with respect to x using the chain rule,- sin y (dy/dx) = 1dy/dx = -1/sin y ... (1)Now, we have sin2y + cos2y ...
The "a" in this case stands for adjacent. The "h" stands for the hypotenuse, which can be found through the pythagorean theorem. In order to find cosine, all you'll need is the adjacent side and the hypotenuse. sine rule When you come across sine, you can find the answer for it ...
