" 1."(7+x)/((1+x)(1+x^(2)))

Resolve (7+x)/((1+x)(1+x^(2))) into partial fractions

The coefficient of x^(7) in (1-x)/((1+x)^(2)) is

Express (7x-1)/((1-x)(1+2x)) in partial fractions.

If (1-x^(7))/(x(1+x^(7)))dx=a ln|x|+b ln|x^(7)+1|+c then a=1,b=(2)/(7) (b) a=-1,b=(2)/(7)a=1,b=-(2)/(7)(d)a=-1,b=-(2)/(7)

int((x^(2)-x-1)/(x)+1)^(K+7)((x^(2)+1)/(x^(2)))dx is equal to ………………
