The unit circle gif came around again and I can wrap my head around sin and cos as measures of the x and y components of the unit circle. but the tangent doesn’t seem to be a measurement of anything and I have never really understood that.
TIA
In: Mathematics
It is the [length of the tangent](https://www.onlinemathlearning.com/unit-circle.html) to the unit circle.
That’s how it got its name, but in actuality it is just useful to have a third ratio for a right triangle which does not include the hypotenuse. Often you’ll have two of three.
