It is unknown who created the unit circle. Pythagoras did a lot of work related to the unit circle. In ancient times, Greek, Indian, and Arabian mathematicians used the unit circle.
WHAT ARE THE TANGENTS OF ALL COORDINATES IN THE UNIT CIRCLE?
Here is a time-line that shows the history of the unit circle dating back to 250 B.C.

A=u^x/360
If the radius is two. it won't be a unit circle, a unit circle is defined as a circle with radius one.
The unit circle is a circle with its center at the origin and a radius of ' 1 '.
A unit circle is a circle with radius equal to one.
It is unknown who created the unit circle. Pythagoras did a lot of work related to the unit circle. In ancient times, Greek, Indian, and Arabian mathematicians used the unit circle.
A unit circle is not normally called 2 pi. Because the radius length measure of the unit circle is 1 unit, then the circumference of a unit circle is 2*pi, and its area is pi.
A circle can have a unit of length which could be either a measure of its diameter or radius, or of its circumference. Or the circle could have the unit of area.
There really isn't much to memorize. The unit circle is a circle with a radius of 1.
A unit circle is one that has a radius of one. One = Unit, and hence the name.
WHAT ARE THE TANGENTS OF ALL COORDINATES IN THE UNIT CIRCLE?
Since the radius of the unit circle is 1, the circumference is 2 x pi.
unit in earth science used for measuring angles in a circle or sphere?
A 'unit cube'. Just like a circle with radius 1 and center at (0,0) is a 'unit circle'.
