Datrys varepsilon_{c}=mc^2

$$\varepsilon _ { c } = m c ^ { 2 }$$

Datrys ar gyfer m (complex solution)

$$\left\{\begin{matrix}m=\frac{\epsilon _{c}}{c^{2}}\text{, }&c\neq 0\\m\in \mathrm{C}\text{, }&\epsilon _{c}=0\text{ and }c=0\end{matrix}\right.$$

Camau ar gyfer Datrys Hafaliad Llinol

Cyfnewidiwch yr ochrau fel bod yr holl dermau newidiol ar yr ochr chwith.

$$mc^{2}=\epsilon _{c}$$

Mae'r hafaliad yn y ffurf safonol.

$$c^{2}m=\epsilon _{c}$$

Rhannu’r ddwy ochr â c^{2}.

$$\frac{c^{2}m}{c^{2}}=\frac{\epsilon _{c}}{c^{2}}$$

Mae rhannu â c^{2} yn dad-wneud lluosi â c^{2}.

$$m=\frac{\epsilon _{c}}{c^{2}}$$

Datrys ar gyfer m

$$\left\{\begin{matrix}m=\frac{\epsilon _{c}}{c^{2}}\text{, }&c\neq 0\\m\in \mathrm{R}\text{, }&\epsilon _{c}=0\text{ and }c=0\end{matrix}\right.$$
