I have tried to use Mathematica on evaluating complete elliptic integral of the first kind by entering:

Integrate[1/Sqrt[1-(r^2 Sin[\[Phi]]^2)/x^2],{\[Phi],0,\[Pi]/2},Assumptions->Re[r^2/x^2]>1&&r^2/x^2\[Element]Reals]

Mathematica has given me the answer:

But to me, the correct answer should be

Can you please show me where I have gone wrong?
