As per the diagram, Cosine rules to find the length of the sides a, b & c of the triangle ABC is given by; a2= b2+ c2– 2bc cosx b2= a2+ c2– 2ac cos y c2= a2+ b2– 2ab cos z Similarly, to find the angles x, y and z, these formulae can be re-written as : ...

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: ...
Consequently, cos ɸ and sin ɸ may be considered the cosine and sine of an angle. In general, the argument of a trigonometric function is considered to be a number, which may be regarded geometrically as the length of an arc or the radian measure of an angle. If the argument is ...
