" 6."int(dx)/(1-x-x^(2))

int(dx)/((1-6x-9x^(2)))

int(dx)/(x(x^(6)+1))

Evaluate : (i) int(dx)/((1-4x^(2))) (ii) int(dx)/((32-2x^(2))) (iii) int(x^(2))/((1-x^(6)))dx

int(1)/(6+5x-6x^(2))dx

int(6)/((1-2x)^(3))dx

int(x^(6))/(x^(2)+1)dx

If int(x+2)/(2x^(2)+6x+5)dx =P int(4x+6)/(2x^(2)+6x+5)dx+(1)/(2) int (dx)/(2x^(2)+6x+5') Then the value of P is

int(1-x^6)/(1-x)dx

Evaluate int(1+x^(6))/(1+x^(2))dx
