The Cosine Rule Missing Sides Youtube Corbettmaths this video shows how to find missing sides using the cosine rule. there is another video for missing angles. The cosine rule, also known as the law of cosines, relates all 3 sides of a triangle with an angle of a triangle. it is most useful for solving for missing information in a triangle. for example, if all three sides of the triangle are known, the cosine rule allows one to find any of the angle measures. similarly, if two sides and the angle between them is known, the cosine rule allows …. The corbettmaths video tutorial on using the cosine rule to find the size of missing sides. welcome; videos and worksheets; primary; 5 a day. 5 a day gcse 9 1; 5 a. The first of these two revision videos explains how to find the missing sides in any triangle using the cosine rule. the second video shows you how to use the same rule to find the angles when they are missing. the latter requires a good understanding of rearranging formulae. cosine rule finding missing sides (corbett maths).

Cosine rule. examples, videos, and solutions to help gcse maths students learn how to use the cosine rule to find either a missing side or a missing angle of a triangle. the following diagram shows the cosine rule that can be used to find a missing angle or a missing side of a triangle. scroll down the page for more examples and solutions. Example 1. calculate the length of side ac of the triangle shown below. solution. because we want to calculate the length, we will therefore use the. cosine rule in the form of; ⇒ (b) 2 = [a 2 c 2 – 2ac] cos (b) by substitution, we have, b 2 = 4 2 3 2 – 2 x 3 x 4 cos (50) b 2 = 16 9 – 24cos50.
