int(dx)/(x^(2)sqrt(a^(2)+x^(2)))

int(dx)/(x^(2)sqrt(x^(2)+a^(2)))=

int(dx)/(x^2sqrt(a^2+x^2))=

The integral int(x dx)/(2-x^(2)+sqrt(2-x^(2))) equals:

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

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

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

The value of the expression (int_(0)^(a)x^(4)sqrt(a^(2)-x^(2))dx)/(int_(0)^(a)x^(2)sqrt(a^(2)-x^(2))dx)=

If int((x-1)dx)/(x^(2)sqrt(2x^(2)-2x+1))=(sqrt(f(x)))/(g(x))+C, then f(x)=2x^(2)-2x+1 (b) g(x)=x+1g(x)=x( d) f(x)=sqrt(2x^(2)-2x)

int(dx)/(x sqrt(x^(2)-a^(2)))

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