Solve the following equation for :

### Solution

In the right-hand side we write for :

We could also have applied other formulas but this one fits better to the left-hand side.

The equation:

has the following solution (within the domain):

or:

The equation:

has the solution:

(this one does not lie in the domain and is not valid)

or:

Again, this solution does not lie in the domain and is not valid.

Thus the solutions are:

or:
