If you draw a unit circle, the sine function can be expressed as the y-coordinate of a point on the circle; the cosine function as the x-coordinate.
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 '.
Yes, but only if the argument of the sine function is in radians.
The period of a trigonometric function, since it depends on the angle of a ray centered in a unit circle, is 2 pi radians or 360 degrees.

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.
The unit circle is a circle that can be used to find trigonometric functions. The equation of the unit circle is x^2 + y^2 = 1. So it is any circle with radius 1.
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.
