Passi għall-Użu ta' Regola Derivattiva għal Kwozjent

Biex iżżid jew tnaqqas l-espressjonijiet, espandihom biex id-denominaturi tagħhom ikunu l-istess. Immultiplika x b'\frac{x-1}{x-1}.

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

Billi \frac{x\left(x-1\right)}{x-1} u \frac{1}{x-1} għandhom l-istess denominatur, żidhom billi żżid in-numeraturi tagħhom.

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

Agħmel il-multiplikazzjonijiet fi x\left(x-1\right)+1.

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

Għal kwalunkwe żewġ funzjonijiet differenzjabbli, id-derivattiv tal-kwozjent ta' żewġ funzjonijiet huwa d-denominatur immultiplikat bid-derivattiv tan-numeratur minus in-numeratur immultiplikat bid-derivattiv tad-denominatur, kollha diviżi bid-denominatur kwadrat.

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

Id-derivattiv ta' polynomial huwa s-somma tad-derivattivi tat-termini tiegħu. Id-derivattiv ta' kwalunkwe terminu kostanti huwa 0. Id-derivattiv ta' ax^{n} huwa nax^{n-1}.

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

Issimplifika.

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

Immultiplika x^{1}-1 b'2x^{1}-x^{0}.

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

Immultiplika x^{2}-x^{1}+1 b'x^{0}.

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

Biex timmultiplika l-qawwa tal-istess bażi, żid l-esponenti tagħhom.

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

Issimplifika.

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

Ikkombina termini simili.

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

Għal kwalunkwe terminu t, t^{1}=t.

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

Iddifferenzja w.r.t. x

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