Riješi f=sqrt{1+x/1-x}

$$f = \sqrt { \frac { 1 + x } { 1 - x } }$$

Izračunaj f (complex solution)

$$f=\sqrt{\frac{x+1}{1-x}}$$

$$x\neq 1$$

Izračunaj x (complex solution)

$$x=-\frac{1-f^{2}}{f^{2}+1}$$

$$f\neq i\text{ and }\left(f=0\text{ or }arg(f)<\pi \right)\text{ and }f\neq -i$$

Izračunaj f

$$f=\sqrt{\frac{x+1}{1-x}}$$

$$x\geq -1\text{ and }x<1$$

Izračunaj x

$$x=-\frac{1-f^{2}}{f^{2}+1}$$

$$f\geq 0$$
