Unit Circle. The "Unit Circle" is a circle with a radius of 1. Being so simple, it is a great way to learn and talk about lengths and angles. The center is put on a graph where the x axis and y axis cross, so we get this neat arrangement here.

17 Σεπ 2021 · The unit circle makes things easier, not harder. The unit circle is simple, it's a circle with a radius of 1. So why is it so useful? We can see things in their simplest form. Let's get an intuition of the unit circle by using the interactive below.
In trigonometry, the unit circle is a circle with of radius 1 that is centered at the origin of the Cartesian coordinate plane. The unit circle helps us generalize trigonometric functions, making it easier for us to work with them since it lets us find sine and cosine values given a point on the unit circle.
Relates the unit circle to the method for finding trig ratios in any of the four quadrants. Explains why mathematicians use the unit circle.
