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

Simplify : (sqrt(x^(2)+y^(2))-y)/(x-sqrt(x^(2)-y^(2)))-:(sqrt(x^(2)-y^(2))+x)/(sqrt(x^(2)+y^(2))+y)

Simplify : (sqrt(x^(2)+y^(2))-y)/(x-sqrt(x^(2)+y^(2)))-:(sqrt(x^(2)+y^(2))+x)/(sqrt(x^(2)+y^(2))+y)

Simplify : (sqrt(x^(2)+y^(2))-y)/(x-sqrt(x^(2)-y^(2))) div (sqrt(x^(2)-y^(2))+x)/(sqrt(x^(2)+y^(2))+y)

Evaluate: lim_(x to oo) (sqrt(x+2)-sqrt(2))/(x) .

The number of integer values of x in R such that (sqrt(2-x^(2)-x))/(2x+sqrt(x))<(sqrt(2-x^(2)-x))/(x+sqrt(x))

(d)/(dx ) {(sqrt(a^(2)+x ^(2))+ sqrt(a ^(2) -x ^(2)))/(sqrt(a ^(2) + x ^(2)) - sqrt(a ^(2) - x ^(2)))}=

Solve the equations: Q. sqrt((x^(2)+2)/(x^(2)-2))+6sqrt((x^(2)-2)/(x^(2)+2))=5 .

lim_(xrarr2)(sqrt(x+2)-sqrt(x-2))/(x+2) is equal to

int(dx)/(1+sqrt(x^(2)+2x+2)) = (A/7)(log|x+1+sqrt(x^(2)+2x+2)|)-(sqrt(x^(2)+2x+2)-1)/(x+1)+C , then A equal to.
