Angle;
abc,cda ; acb,cad ;bac;dca.
Given ABC = 1, find a / [ABC + AB + A + 1] + B / BCD + BC + B + 1] + C / [CDA + CD + C + 1] + D / [DAB + Da + D + 1]
Come on, thank you
The process should be detailed
a/(abc+ab+a+1)+b/(bcd+bc+b+1)+c/(cda+cd+c+1)+d/(dab+da+d+1) =a/(1/d+ab+a+1)+b/(bcd+bc+b+1)+c/(1/b+cd+c+1)+d/(dab+da+d+1) =ad/(abd+ad+d+1)+b/(bcd+bc+b+1)+bc/(bcd+bc+b+1)+d/(dab+da+d+1) =(ad+d)/(abd+ad+...
