Lineāra vienādojuma risināšanas darbības

Reiziniet d un d, lai iegūtu d^{2}.

$$\frac{\mathrm{d}(y)}{\mathrm{d}y}d^{2}yx=1-\frac{1}{\sqrt{2}}$$

Atbrīvojieties no iracionalitātes saucēju ar \frac{1}{\sqrt{2}}, reizinot skaitītāju un saucēju ar \sqrt{2}.

$$\frac{\mathrm{d}(y)}{\mathrm{d}y}d^{2}yx=1-\frac{\sqrt{2}}{\left(\sqrt{2}\right)^{2}}$$

Skaitļa \sqrt{2} kvadrāts ir 2.

$$\frac{\mathrm{d}(y)}{\mathrm{d}y}d^{2}yx=1-\frac{\sqrt{2}}{2}$$

Reiziniet vienādojuma abas puses ar 2.

$$2\frac{\mathrm{d}(y)}{\mathrm{d}y}d^{2}yx=2-\sqrt{2}$$

Vienādojums ir standarta formā.

$$2yd^{2}x=2-\sqrt{2}$$

Daliet abas puses ar 2d^{2}y.

$$\frac{2yd^{2}x}{2yd^{2}}=\frac{2-\sqrt{2}}{2yd^{2}}$$

Dalīšana ar 2d^{2}y atsauc reizināšanu ar 2d^{2}y.

$$x=\frac{2-\sqrt{2}}{2yd^{2}}$$

Atrast d (complex solution)

$$d=-\frac{\sqrt{4-2\sqrt{2}}x^{-\frac{1}{2}}y^{-\frac{1}{2}}}{2}$$

$$d=\frac{\sqrt{4-2\sqrt{2}}x^{-\frac{1}{2}}y^{-\frac{1}{2}}}{2}\text{, }x\neq 0\text{ and }y\neq 0$$

Atrast d

$$d=\frac{\sqrt{\frac{4-2\sqrt{2}}{xy}}}{2}$$

$$d=-\frac{\sqrt{\frac{4-2\sqrt{2}}{xy}}}{2}\text{, }\left(x>0\text{ and }y>0\right)\text{ or }\left(y<0\text{ and }x<0\right)$$
