1/(1+x^(b-a)+x^(c-a) )+1/(1+x^(a-b)+x^(c-b) )+1/(1+x^(b-c)+x^(a-c) )=1
The text form of this sum (1/ (1+x^(b-a)+x^(c-a) )+(1/(1+x^(a-b)+x^(c-b) )+(1/(1+x^(b-c)+x^(a-c) )=1 is given below. So that students may not get confused with the text form of the sum. Watch video or see this solution:First term: (1/ (1+x^(b-a)+x^(c-a) )=(1/ (1+x^b*x^a)+x^c*x^a))=(x^a/ (x^a+x^b+x^c))Second term: (1/ Read more
