Réitigh 2t^3/3-3t^2+2t+4

$$\frac { 2 t ^ { 3 } } { 3 - 3 t ^ { 2 } + 2 t + 4 }$$

Difreálaigh w.r.t. t

$$\frac{2t^{2}\left(3t^{2}-4t-21\right)}{-9t^{4}+12t^{3}+38t^{2}-28t-49}$$

Suimigh 3 agus 4 chun 7 a fháil.

$$\frac{\mathrm{d}}{\mathrm{d}t}(\frac{2t^{3}}{7-3t^{2}+2t})$$

Do dhá fheidhm indifreáilte ar bith, is ionann díorthach líon an dá fheidhme agus an t-ainmneoir méadaithe faoi dhíorthach an uimhreora lúide an t-uimhreoir méadaithe faoi dhíorthach an ainmneora, agus iad ar fad roinnte faoin ainmneoir cearnaithe.

$$\frac{\left(-3t^{2}+2t^{1}+7\right)\frac{\mathrm{d}}{\mathrm{d}t}(2t^{3})-2t^{3}\frac{\mathrm{d}}{\mathrm{d}t}(-3t^{2}+2t^{1}+7)}{\left(-3t^{2}+2t^{1}+7\right)^{2}}$$

Is ionann díorthach iltéarmaigh agus suim dhíorthaigh a théarmaí. Is ionann díorthach téarma thairisigh agus 0. Is ionann díorthach ax^{n} agus nax^{n-1}.

$$\frac{\left(-3t^{2}+2t^{1}+7\right)\times 3\times 2t^{3-1}-2t^{3}\left(2\left(-3\right)t^{2-1}+2t^{1-1}\right)}{\left(-3t^{2}+2t^{1}+7\right)^{2}}$$

Simpligh.

$$\frac{\left(-3t^{2}+2t^{1}+7\right)\times 6t^{2}-2t^{3}\left(-6t^{1}+2t^{0}\right)}{\left(-3t^{2}+2t^{1}+7\right)^{2}}$$

Méadaigh -3t^{2}+2t^{1}+7 faoi 6t^{2}.

$$\frac{-3t^{2}\times 6t^{2}+2t^{1}\times 6t^{2}+7\times 6t^{2}-2t^{3}\left(-6t^{1}+2t^{0}\right)}{\left(-3t^{2}+2t^{1}+7\right)^{2}}$$

Méadaigh 2t^{3} faoi -6t^{1}+2t^{0}.

$$\frac{-3t^{2}\times 6t^{2}+2t^{1}\times 6t^{2}+7\times 6t^{2}-\left(2t^{3}\left(-6\right)t^{1}+2t^{3}\times 2t^{0}\right)}{\left(-3t^{2}+2t^{1}+7\right)^{2}}$$

Chun cumhachtaí an bhoinn chéanna a mhéadú, suimigh a n-easpónaint.

$$\frac{-3\times 6t^{2+2}+2\times 6t^{1+2}+7\times 6t^{2}-\left(2\left(-6\right)t^{3+1}+2\times 2t^{3}\right)}{\left(-3t^{2}+2t^{1}+7\right)^{2}}$$

Simpligh.

$$\frac{-18t^{4}+12t^{3}+42t^{2}-\left(-12t^{4}+4t^{3}\right)}{\left(-3t^{2}+2t^{1}+7\right)^{2}}$$

Cuir téarmaí cosúla le chéile.

$$\frac{-6t^{4}+8t^{3}+42t^{2}}{\left(-3t^{2}+2t^{1}+7\right)^{2}}$$

Do théarma ar bith t, t^{1}=t.

$$\frac{-6t^{4}+8t^{3}+42t^{2}}{\left(-3t^{2}+2t+7\right)^{2}}$$
