Datrys d/dxleft(x+1/x-1right)

$$\frac{d}{d x } \left(x+ \frac{ 1 }{ x-1 } \right)$$

Enrhifo

$$\frac{x\left(x-2\right)}{\left(x-1\right)^{2}}$$

Camau gan Ddefnyddio Rheol Deilliadol ar gyfer Cyniferydd

I ychwanegu neu dynnu mynegiannau, rhaid i chi eu ehangu i wneud eu enwaduron yr un fath. Lluoswch x â \frac{x-1}{x-1}.

$$\frac{\mathrm{d}}{\mathrm{d}x}(\frac{x\left(x-1\right)}{x-1}+\frac{1}{x-1})$$

Gan fod gan \frac{x\left(x-1\right)}{x-1} a \frac{1}{x-1} yr un dynodydd, adiwch nhw drwy adio eu rhifiaduron.

$$\frac{\mathrm{d}}{\mathrm{d}x}(\frac{x\left(x-1\right)+1}{x-1})$$

Gwnewch y gwaith lluosi yn x\left(x-1\right)+1.

$$\frac{\mathrm{d}}{\mathrm{d}x}(\frac{x^{2}-x+1}{x-1})$$

Ar gyfer unrhyw ddau ffwythiant y mae modd eu gwahaniaethu, deilliad cyniferydd dau ffwythiant yw’r enwadur wedi’i luosi â deilliad yr enwadur wedi’i dynnu o’r rhifiadur wedi’i luosi â deilliad yr enwadur, y cwbl wedi’i rannu â’r enwadur wedi'i sgwario.

$$\frac{\left(x^{1}-1\right)\frac{\mathrm{d}}{\mathrm{d}x}(x^{2}-x^{1}+1)-\left(x^{2}-x^{1}+1\right)\frac{\mathrm{d}}{\mathrm{d}x}(x^{1}-1)}{\left(x^{1}-1\right)^{2}}$$

Deilliad polynomaial yw swm deilliadau ei dermau. Deilliad term cyson yw 0. Y deilliad o ax^{n} yw nax^{n-1}.

$$\frac{\left(x^{1}-1\right)\left(2x^{2-1}-x^{1-1}\right)-\left(x^{2}-x^{1}+1\right)x^{1-1}}{\left(x^{1}-1\right)^{2}}$$

Symleiddio.

$$\frac{\left(x^{1}-1\right)\left(2x^{1}-x^{0}\right)-\left(x^{2}-x^{1}+1\right)x^{0}}{\left(x^{1}-1\right)^{2}}$$

Lluoswch x^{1}-1 â 2x^{1}-x^{0}.

$$\frac{x^{1}\times 2x^{1}+x^{1}\left(-1\right)x^{0}-2x^{1}-\left(-x^{0}\right)-\left(x^{2}-x^{1}+1\right)x^{0}}{\left(x^{1}-1\right)^{2}}$$

Lluoswch x^{2}-x^{1}+1 â x^{0}.

$$\frac{x^{1}\times 2x^{1}+x^{1}\left(-1\right)x^{0}-2x^{1}-\left(-x^{0}\right)-\left(x^{2}x^{0}-x^{1}x^{0}+x^{0}\right)}{\left(x^{1}-1\right)^{2}}$$

I luosi pwerau sy’n rhannu’r un sail, ychwanegwch eu hesbonyddion.

$$\frac{2x^{1+1}-x^{1}-2x^{1}-\left(-x^{0}\right)-\left(x^{2}-x^{1}+x^{0}\right)}{\left(x^{1}-1\right)^{2}}$$

Symleiddio.

$$\frac{2x^{2}-x^{1}-2x^{1}+x^{0}-\left(x^{2}-x^{1}+x^{0}\right)}{\left(x^{1}-1\right)^{2}}$$

Cyfuno termau sydd yr un peth.

$$\frac{x^{2}-2x^{1}}{\left(x^{1}-1\right)^{2}}$$

Ar gyfer unrhyw derm t, t^{1}=t.

$$\frac{x^{2}-2x}{\left(x-1\right)^{2}}$$

Gwahaniaethu w.r.t. x

$$\frac{2}{\left(x-1\right)^{3}}$$
