Question 650759: ((x^2(1+x^2)^(1/2))-(x^2(1+x^2)^(-1/2)))/(1+x^2)
What is the domain of the question above? and also would you be kind enough to show me the steps?
Answer by MathLover1(20850) (Show Source): You can put this solution on YOUR website!

To find the domain, I'll ignore the "" in the numerator (since the numerator

cause division by ) and instead I'll look at the
.
I'll set the denominator equal to , and solve.

The in the solution will be the which would cause
division by . The domain will then be all other .

and

...as you can see here, whatever is, the denominator will NOT be equal
to
so, the domain will be all real numbers from to
