BBC: Using the sine and cosine rules to find a side or angle in a triangle
The trigonometric ratios sine, cosine and tangent are used to calculate angles and sides in right angled triangles. We are now going to extend trigonometry beyond right angled triangles and use it to ...
Using the sine and cosine rules to find a side or angle in a triangle
The cosine rule is: (a^2 = b^2 + c^2 - 2bc \cos{A}) This version is used to calculate lengths. Calculate the length BC. Give the answer to three significant figures. Use the form (a^2 = b^2 + c^2 - ...
