`int\ (7x^8+8x^7)/(x^8+x+1)^2 \ dx=`

int (7x^(8)+8x^(7))/((1+x+x^(8))^(2))dx=f(x)+c rArr f(x)=

int1/(7x^2-8)dx

int (8x^7+8^xlog_e8)/(x^8+8^x)

int (dx)/( (x -8) (x +7)) =

int(x^(2)-8x+7)/((x^(2)-3x-10)^(2))dx

f(x)=int(5x^8+7x^6)/(x^2+1+2x^7)^2dx , if f(0)=0 then find f(1)=1/k. Then k is

If f(x)=int(5x^8+7x^6)/((x^2+1+2x^7)^2)dx, (xge0), f(0)=0 and f(1)=1/K , then the value of K is _______ .

int(7x-8)/(x(x-1)^(2))dx

int(dx)/(8-7x^2)=

The value of int (cos 7x-cos 8x)/(1+2 cos 5x)dx , is
