Use cosine, sine and tan to calculate angles and sides of right-angled triangles in a range of contexts.

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 ...

There are three main trigonometric functions - Sine θ (sin θ), Cosine θ (cos θ) and Tangent θ (tan θ). Sin θ - Ratio of Perpendicular to Hypotenuse Cos θ - Ratio of Base to Hypotenuse ...
