`int(dx)/(1+(x^(2))/(4))`

int(1)/(1+(x^(2))/(4))dx

int(dx)/((x^(4)-1)^(2))

If int(dx)/((x-1)^((3)/(4))(x+2)^((5)/(4)))=k((x-1)/(x+2))^((1)/(4))+c , then the number of divisors of 30k is

int(1)/(1+4x^(2))dx

int(dx)/((x^(2)+1)(x^(2)+4))=

int(dx)/((1-2^(x))^(4))dx

Integration of rational functions I = int(dx)/((x^(2)+1)(x^(2)+4))

Evaluate : int (dx)/((2x+1)(x^(2)+4))

int(3dx)/((x^(2)+1)(x^(2)+4))=

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