$$f i = \frac { n i } { N } \quad f j \frac { n } { N }$$

Réitigh do f.

$$\left\{\begin{matrix}f=0\text{, }&N\neq 0\\f\in \mathrm{C}\text{, }&\left(n=-j^{-\frac{1}{2}}N\text{ or }n=j^{-\frac{1}{2}}N\right)\text{ and }j\neq 0\text{ and }N\neq 0\end{matrix}\right.$$

Céimeanna chun Cothromóidí Líneacha a Réiteach

Méadaigh an dá thaobh den chothromóid faoi N.

$$fiN=nifj\times \frac{n}{N}$$

Scríobh n\times \frac{n}{N} mar chodán aonair.

$$fiN=\frac{nn}{N}ifj$$

Méadaigh n agus n chun n^{2} a fháil.

$$fiN=\frac{n^{2}}{N}ifj$$

Scríobh \frac{n^{2}}{N}f mar chodán aonair.

$$fiN=\frac{n^{2}f}{N}ij$$

Scríobh \frac{n^{2}f}{N}j mar chodán aonair.

$$fiN=\frac{n^{2}fj}{N}i$$

Bain \frac{n^{2}fj}{N}i ón dá thaobh.

$$fiN-\frac{n^{2}fj}{N}i=0$$

Méadaigh an dá thaobh den chothromóid faoi N.

$$fiNN-n^{2}fji=0$$

Athordaigh na téarmaí.

$$iNNf-ifjn^{2}=0$$

Méadaigh N agus N chun N^{2} a fháil.

$$iN^{2}f-ifjn^{2}=0$$

Comhcheangail na téarmaí ar fad ina bhfuil f.

$$\left(iN^{2}-ijn^{2}\right)f=0$$

Roinn 0 faoi iN^{2}-ijn^{2}.

$$f=0$$

Réitigh do N.

$$\left\{\begin{matrix}N=-\sqrt{j}n\text{; }N=\sqrt{j}n\text{, }&j\neq 0\text{ and }n\neq 0\\N\neq 0\text{, }&f=0\end{matrix}\right.$$
