um can anyone out there explain the above post. I'm having troubles understanding how 1/(x^b + x^-c + 1) = x^c/(x^(b + c) + 1 + x^c) = x^c/(x^-a + 1 + x^c) ; 1/(x^b + x^-c + 1) = 1/(x^b + (1/x^c )+ 1) = 1//((x^b)(x^c) + 1 + x^c)/x^c = x^c/(x^(b + c) + 1 + x^c) = x^c/(x^-a + 1 + c^c) [b + c = -a giv...

The value of 1/(x^b + x^-c + 1) +1/( x^c + x^-a + 1) + 1/(x^a + x^-b + 1) , given that a + b + c = 0 , is : 1/(x^b + x^-c + 1) = x^c/(x^(b + c) + 1 + x^c) = x^c/(x^-a + 1 + x^c) ; because [b + c = -a] 1/(x^a + x^-b + 1) = x^(b + c)/(x^(a + b+ c) + x ^c + x^(b + c)) = x^-a/(1 + x^c + x^-a) Add all t...
