f(x)+f( 1-x)= 1/(2^x-√2)+ 1/(2^( 1-x)-√2)

= 1/(2^x-√2)+ 1/[(2/2^)-√2]

= 1/(2^x-√2)+2^x/(2-2^x*√2)

=√2/(2^x*√2-2)+2^x/(2-2^x*√2)

=√2/(2^x*√2-2)-2^x/(2^x*√2-2)

=(√2-2^x)/(2^x*√2-2)

=-(2^x-√2)/√2(2^x-√2)

=- 1/√2

=-√2/2

Sum of independent variables =1(x+1-x =1)

Sum of function values =-√2/2

s = f(-5)+f(-4)+……+f(0)+f( 1)+……+f(5)+f(6)

s = f(6)+f(5)+…+f( 1)+f(0)+…+f(-4)+f(-5)add。

2S =-√2/2-√2/2……-√2/2-√2/2……-√2/2-√2/2 =-6√2

S=-3√2
