int(sqrt(1+x^(4)))/(1-x^(4))dx

If int_((-1)/(sqrt3))^(1//sqrt3)(x^(4))/(1-x^(4))cos^(-1)((2x)/(1+x^(2)))dx=k , then int_(0)^(1//sqrt3)(x^(4))/(1-x^(4))dx the value of k is equal to

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

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

int (1-sqrt(x))/(1+(x)^(1/4))dx=

int(1)/(x sqrt(x^(4)-b^(4)))dx

(i) int ((1+x)^(3))/(sqrt(x))dx " "(ii) int((1+x)^(3))/(x^(4)) dx

(i) int ((1+x)^(3))/(sqrt(x))dx " "(ii) int((1+x)^(3))/(x^(4)) dx

int(sqrt(x))/(1+4sqrt(x^(3)))dx is equal to

int(sqrt(x))/(1+4sqrt(x^(3)))dx is equal to

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