Datrys y/2y^2+7y+6

$$\frac { y } { 2 y ^ { 2 } + 7 y + 6 }$$

Gwahaniaethu w.r.t. y

$$\frac{2\left(3-y^{2}\right)}{\left(\left(y+2\right)\left(2y+3\right)\right)^{2}}$$

Camau gan Ddefnyddio Rheol Deilliadol ar gyfer Cyniferydd

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.

$$\frac{\left(2y^{2}+7y^{1}+6\right)\frac{\mathrm{d}}{\mathrm{d}y}(y^{1})-y^{1}\frac{\mathrm{d}}{\mathrm{d}y}(2y^{2}+7y^{1}+6)}{\left(2y^{2}+7y^{1}+6\right)^{2}}$$

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

$$\frac{\left(2y^{2}+7y^{1}+6\right)y^{1-1}-y^{1}\left(2\times 2y^{2-1}+7y^{1-1}\right)}{\left(2y^{2}+7y^{1}+6\right)^{2}}$$

Symleiddio.

$$\frac{\left(2y^{2}+7y^{1}+6\right)y^{0}-y^{1}\left(4y^{1}+7y^{0}\right)}{\left(2y^{2}+7y^{1}+6\right)^{2}}$$

Lluoswch 2y^{2}+7y^{1}+6 â y^{0}.

$$\frac{2y^{2}y^{0}+7y^{1}y^{0}+6y^{0}-y^{1}\left(4y^{1}+7y^{0}\right)}{\left(2y^{2}+7y^{1}+6\right)^{2}}$$

Lluoswch y^{1} â 4y^{1}+7y^{0}.

$$\frac{2y^{2}y^{0}+7y^{1}y^{0}+6y^{0}-\left(y^{1}\times 4y^{1}+y^{1}\times 7y^{0}\right)}{\left(2y^{2}+7y^{1}+6\right)^{2}}$$

$$\frac{2y^{2}+7y^{1}+6y^{0}-\left(4y^{1+1}+7y^{1}\right)}{\left(2y^{2}+7y^{1}+6\right)^{2}}$$

Symleiddio.

$$\frac{2y^{2}+7y^{1}+6y^{0}-\left(4y^{2}+7y^{1}\right)}{\left(2y^{2}+7y^{1}+6\right)^{2}}$$

Cyfuno termau sydd yr un peth.

$$\frac{-2y^{2}+6y^{0}}{\left(2y^{2}+7y^{1}+6\right)^{2}}$$

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

$$\frac{-2y^{2}+6y^{0}}{\left(2y^{2}+7y+6\right)^{2}}$$

Ar gyfer unrhyw derm t ac eithrio 0, t^{0}=1.

$$\frac{-2y^{2}+6\times 1}{\left(2y^{2}+7y+6\right)^{2}}$$

Ar gyfer unrhyw derm t, t\times 1=t a 1t=t.

$$\frac{-2y^{2}+6}{\left(2y^{2}+7y+6\right)^{2}}$$

Enrhifo

$$\frac{y}{\left(y+2\right)\left(2y+3\right)}$$
