Tangent on the Unit Circle

Website: https://math-stuff.com

We start by recalling how can the tangent and the cotangent of an acute angle be expressed using the sine and the cosine. We then use those expressions as definitions of the tangent and cotangent of any angle. We also show how to visually represent the tangent of an angle on the unit circle.
