Answer:

Step-by-step explanation:

Answer 2

1 / { 1 + x^( a - b )} + 1 / { 1 + x^(b - a )} = 1

LHS = 1 / { 1 + x^( a - b )} + 1 / { 1 + x^-( a - b )}

=> 1 / { 1 + x^( a - b )} + 1 / { 1 + 1 / x^( a- b )}

=>[ 1 / { 1 + x^( a - b )}] + [ 1 / { x^ (a - b ) + 1 } / x^( a - b ) ]

=> [ 1 / { 1 + x^( a - b )}] + [ x^ ( a - b ) / x^ ( a - b ) +1 ]

=> [ 1 + x^ ( a - b ) ] / [ 1 + x^ ( a - b )]

=> 1

=> R. H. S.

Hence, PROVED.
