The derivation of some exact formulas used, assuming some symmetries, with
enough detail to follow is at
 proof_new.txt .
At proof_new.txt enough progress is made to check the expressions; further
blazing into new territory is at plato.txt where additional expressions are
derived.  They are rendered in MathML at pentagon.xml.

Calculators using the exact formulas for the pentagon, dodecahedron, icosahedron, and an other example available, as well as an illustration. are available.

Thought for the day: The product of the cosines of the angle between the normals to the faces of the dodecahedron and icosahedron is

\frac{\sqrt{5}}{5}

◦

\frac{\sqrt{5}}{3}

\frac{1}{3}

. Another amazing expression for π is

π = 3 + \frac{1^{2}}{6 +} \frac{3^{2}}{6 +} \frac{5^{2}}{6 +} \frac{7^{2}}{6 +} \frac{9^{2}}{6 +}
