Réitigh dθ/dx+dz/dθ=phidθ

$$\frac { d \theta } { d x } + \frac { d z } { d \theta } = \phi d \theta$$

Réitigh do d. (complex solution)

$$\left\{\begin{matrix}\\d=0\text{, }&\text{unconditionally}\\d\in \mathrm{C}\text{, }&\theta =0\text{ or }ϕ=0\end{matrix}\right.$$

Céimeanna chun Cothromóidí Líneacha a Réiteach

Athraigh na taobhanna ionas go mbeidh na téarmaí inathraitheacha ar fad ar an taobh clé.

$$ϕd\theta =\frac{\mathrm{d}(\theta )}{\mathrm{d}x}+\frac{\mathrm{d}(z)}{\mathrm{d}\theta }$$

Tá an chothromóid i bhfoirm chaighdeánach.

$$\theta ϕd=0$$

Roinn 0 faoi ϕ\theta .

$$d=0$$
