Правда, надо учитывать, что это лишь видимые эффекты.

( tan(30°) = sqrt(3)/3 ).
( tan(30°) = sqrt(3)/3 ).

formula: vlength=sqrt(vdot(a,a)).
formula: length=sqrt(vdot(a,a)).

ra = ri * ( 1 + 2*sqrt(3)/3 ).
ra = ri * ( 1 + 2*sqrt(3)/3 ).

r = a / 2 * sqrt( 5 + 2*sqrt(2));
r = a / 2 * sqrt( 5 + 2*sqrt(2));

angle(0,a,d) = degrees( atan(sqrt(2)));
angle(0,a,d) = degrees( atan(sqrt(2)));

c = sqrt( pow( a , 2) + pow( b , 2 ) ) .

= 10 * [sqrt(n)/sqrt(k)] * [1+log(b+0.25)] = 10 * [sqrt(150)/sqrt(3)] * [1+log(20+0.25)] = 10 * sqrt(50) * (1+1.31) = 10 * 7.071 * 2.31 = 163.09 (rounded up)
= 10 * [radq(n)/radq(k)] * [1+log(b+0,25)] = 10 * [radq(150)/radq(3)] * [1+log(20+0,25)] = 10 * radq(50) * (1+1,31) = 10 * 7,071 * 2,31 = 163,09 (arrotondato)
