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

Datrys ar gyfer f

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

Camau ar gyfer Datrys Hafaliad Llinol

Lluoswch ddwy ochr yr hafaliad â N.

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

Mynegwch n\times \frac{n}{N} fel ffracsiwn unigol.

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

Lluosi n a n i gael n^{2}.

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

Mynegwch \frac{n^{2}}{N}f fel ffracsiwn unigol.

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

Mynegwch \frac{n^{2}f}{N}j fel ffracsiwn unigol.

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

Tynnu \frac{n^{2}fj}{N}i o'r ddwy ochr.

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

Lluoswch ddwy ochr yr hafaliad â N.

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

Aildrefnu'r termau.

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

Lluosi N a N i gael N^{2}.

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

Cyfuno pob term sy'n cynnwys f.

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

Rhannwch 0 â iN^{2}-ijn^{2}.

$$f=0$$

Datrys ar gyfer N

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