In 18th century;
Mr. Leonhard Euler,
and, Mrs. Leonhard Euler (Katharina Gsell),
were a married couple.
Politically speaking, as a married couple, they were involved in this =>
1) [ e2i*π - 1 ] = [ ei*π + tan(π/4) ] = [ e2i*π - 1 ]
2) [ e^(i*π) + tan(ninety-by-two)]
= [((√3+i√2)*(√3-i√2)) - ((3+2)*(3-2))]
= [5 - 5] = [five - cinque]
3) [e^(i*π)) + tan(π/4)] = [(√a+i√b)(√a-i√b)] – [(a+b)(a-b)]
= [(a+b)] - [(a+b)(tan(90/2))]
for, any usual (a-b) = tan(π/4);
while four_color_theorem, has been solved.
4) in an, eight_planet_solar_system,
where the first three vowels, are in the third equation, along with the first consonant.
So later, three consonants, participate with one vowel,
while tan(pie_by_four) is not a prime number.
And here is some mathematics, validating, Noether's theorem.

I studied this in 2001-02-03, as an engineering student,
and solved four_colour_theorem myself, in 2001-02. OK.
And for example, the following are four-variables, at the same 'time' =>
Angle within a regular polygon of a-sides = [(a-2)/a]*(pi); while summation = 1 + 2 + 3 + ... + (a-1) + a = a*(a+1)/2;
Angle within a regular polygon of b-sides = [(b-2)/b]*(pi); while summation = 1 + 2 + 3 + ... + (b-1) + b = b*(b+1)/2;
Angle within a regular polygon of c-sides = [(c-2)/c]*(pi); while summation = 1 + 2 + 3 + ... + (c-1) + c = c*(c+1)/2;
Angle within a regular polygon of d-sides = [(d-2)/d]*(pi); while summation = 1 + 2 + 3 + ... + (d-1) + d = d*(d+1)/2;

Politically speaking, I (male) do not like,
"the latest greatest" "female plagiarism license"
about an isosceles triangle, involving transcendental numbers,
which I was already aware of, before 2003.
