👉 Coshers are mathematical constants that represent the area of a circle with radius $r$ when expressed in terms of its circumference. Specifically, they can be defined as: $$\cos(x) = \frac{1}{2} \left( 1 + \sqrt{1 - \sin^2(x)} \right) $$ where $\sin(x)$ is the sine function and $x$ is an angle in radians. Coshers are also known as the "Herm
