1) Подставляем c=1/2:
3(1/2)^2 - 1/2 + 3/(1/2)^3 - 1 - 1/(1/2)^2 + 1 + 2/(1-1/2)
= 3*(1/4) - 1/2 + 3/(1/8) - 1 - 1/(1/4) + 1 + 2/(1/2)= 3/4 - 1/2 + 24/1 - 1 - 4/1 + 1 + 4/1= 3/4 - 1/2 + 24 - 1 - 4 + 1 + 4= 3/4 - 1/2 + 24 - 1 - 4 + 1 + 4= 0.75 - 0.5 + 24 - 1 - 4 + 1 + 4= 0.25 + 24 - 1 - 4 + 1 + 4= 24.25 - 1 - 4 + 1 + 4= 23.25 - 4 + 1 + 4= 19.25 + 1 + 4= 20.25 + 4= 24.25

= 3/4 - 1/2 + 24/1 - 1 - 4/1 + 1 + 4/1
= 3/4 - 1/2 + 24 - 1 - 4 + 1 + 4
= 3/4 - 1/2 + 24 - 1 - 4 + 1 + 4
= 0.75 - 0.5 + 24 - 1 - 4 + 1 + 4
= 0.25 + 24 - 1 - 4 + 1 + 4
= 24.25 - 1 - 4 + 1 + 4
= 23.25 - 4 + 1 + 4
= 19.25 + 1 + 4
= 20.25 + 4
= 24.25
