## Inverse trigonometric equation

 Quote by haruspex Nothing special. It's just a quadratic equation in x; solve it with the usual formula. If it's messy, it's messy.
You can't simply say that I cannot get rid of that square root. Please help me. Its not even a perfect square. Should I leave it this way?

If n=0, then the discriminant is a perfect square. I found no other cases. Also, the discriminant is positive for all values of n.

So as haruspex said, it's a messy result.

OK so you want me to continue with that square root.

That's about all there is to do, but you can't do much simplifying.
