Similarly / = is a constructible angle because 12 is a power of two (4) times a Fermat prime (3). But π / 9 = 20 ∘ {\displaystyle \pi /9=20^{\circ }} is not a constructible angle, since 9 = 3 ⋅ 3 {\displaystyle 9=3\cdot 3} is not the product of distinct Fermat primes as it contains 3 as a factor twice, and neither is π / 7 ≈ 25.714 ∘ ...
A formula for computing the trigonometric identities for the one-third angle exists, but it requires finding the zeroes of the cubic equation 4x 3 − 3x + d = 0, where is the value of the cosine function at the one-third angle and d is the known value of the cosine function at the full angle.

A mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. [1]
