Riješi y=log_{2}({sqrt{4-x^2}})

$$y = \log_{ 2 }({ \sqrt{ 4- { x }^{ 2 } } })$$

Izračunaj x (complex solution)

$$x=-\sqrt{4-4^{y}}$$

$$x=\sqrt{4-4^{y}}\text{, }-2\pi \lfloor \frac{\ln(2)Im(y)}{2\pi }\rfloor +\ln(2)Im(y)<\pi \text{ and }Im(\ln(2^{y}))-\ln(2)Im(y)=0$$

Izračunaj y (complex solution)

$$y=\log_{2}\left(\sqrt{4-x^{2}}\right)$$

$$x\neq -2\text{ and }x\neq 2$$

Izračunaj x

$$x=\sqrt{4-4^{y}}$$

$$x=-\sqrt{4-4^{y}}\text{, }y\leq 1$$

Izračunaj y

$$y=\frac{\log_{2}\left(4-x^{2}\right)}{2}$$

$$|x|<2$$
