Evalute : `int(dx)/((x-1)sqrt(x^2-1))`.

Evalute int(1)/(sqrt(x+3)-sqrt(x-4))dx.

Evalute int (dx)/sqrt(16-2x-2x^2

Evalute int(dx)/sqrt(7-6x-x^2)

Evalute int (dx)/sqrt(15-8x^2)

Evalute : int(1-x^2)/(x(1-2x))dx

Find the integral of 1/ sqrt(x^(2)- a^(2)) with respect to x and hence evalute int (dx)/sqrt(x^(2)+ 6x - 7) .

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

Find the integral of 1/sqrt(a^2-x^2) with respect to x, and hence evalute int(dx)/(sqrt(5-4x-x^2)

Evalute: int((1+logx)^2)/(x)dx
