Réitigh ∫ f(x) wrt x=f(x)dx

$$\int f ( x ) d x = f ( x ) d x$$

Réitigh do d.

$$\left\{\begin{matrix}d=\frac{1}{2}+\frac{С}{2fx^{2}}\text{, }&x\neq 0\text{ and }f\neq 0\\d\in \mathrm{R}\text{, }&\left(x=0\text{ or }f=0\right)\text{ and }С=0\end{matrix}\right.$$

Céimeanna chun Cothromóidí Líneacha a Réiteach

Méadaigh x agus x chun x^{2} a fháil.

$$\int fx\mathrm{d}x=fx^{2}d$$

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

$$fx^{2}d=\int fx\mathrm{d}x$$

Tá an chothromóid i bhfoirm chaighdeánach.

$$fx^{2}d=\frac{fx^{2}}{2}+С$$

Roinn an dá thaobh faoi x^{2}f.

$$\frac{fx^{2}d}{fx^{2}}=\frac{\frac{fx^{2}}{2}+С}{fx^{2}}$$

Má roinntear é faoi x^{2}f cuirtear an iolrúchán faoi x^{2}f ar ceal.

$$d=\frac{\frac{fx^{2}}{2}+С}{fx^{2}}$$

Roinn \frac{fx^{2}}{2}+С faoi x^{2}f.

$$d=\frac{1}{2}+\frac{С}{fx^{2}}$$

Réitigh do f.

$$\left\{\begin{matrix}f=\frac{С}{\left(1-d\right)x^{2}}\text{, }&d\neq 1\text{ and }x\neq 0\\f\in \mathrm{R}\text{, }&\left(x=0\text{ or }d=1\right)\text{ and }С=0\end{matrix}\right.$$
