Resolver sin(x2)

$$\sin ( x2 )$$

Diferentziatu x_2 balioarekiko

$$\cos(x_{2})$$

Deribatuaren definizioa erabiltzeko urratsak

f\left(x\right) funtzioetan, \frac{f\left(x+h\right)-f\left(x\right)}{h} funtzioaren limitea da deribatua, h 0 funtziora joaten baita, limitea baldin badago.

$$\frac{\mathrm{d}}{\mathrm{d}x_{2}}(\sin(x_{2}))=\left(\lim_{h\to 0}\frac{\sin(x_{2}+h)-\sin(x_{2})}{h}\right)$$

Erabili baturaren formula sinuan.

$$\lim_{h\to 0}\frac{\sin(x_{2}+h)-\sin(x_{2})}{h}$$

Deskonposatu \sin(x_{2}).

$$\lim_{h\to 0}\frac{\sin(x_{2})\left(\cos(h)-1\right)+\cos(x_{2})\sin(h)}{h}$$

Idatzi berriro limitea.

$$\left(\lim_{h\to 0}\sin(x_{2})\right)\left(\lim_{h\to 0}\frac{\cos(h)-1}{h}\right)+\left(\lim_{h\to 0}\cos(x_{2})\right)\left(\lim_{h\to 0}\frac{\sin(h)}{h}\right)$$

Erabili x_{2} konstantea limiteak kalkulatzean, h funtzioa 0 funtziora doan heinean.

$$\sin(x_{2})\left(\lim_{h\to 0}\frac{\cos(h)-1}{h}\right)+\cos(x_{2})\left(\lim_{h\to 0}\frac{\sin(h)}{h}\right)$$

\lim_{x_{2}\to 0}\frac{\sin(x_{2})}{x_{2}} limitea 1 da.

$$\sin(x_{2})\left(\lim_{h\to 0}\frac{\cos(h)-1}{h}\right)+\cos(x_{2})$$

\lim_{h\to 0}\frac{\cos(h)-1}{h} limitea ebaluatzeko, lehendabizi, biderkatu zenbakitzailea eta izendatzailea \cos(h)+1 balioarekin.

$$\left(\lim_{h\to 0}\frac{\cos(h)-1}{h}\right)=\left(\lim_{h\to 0}\frac{\left(\cos(h)-1\right)\left(\cos(h)+1\right)}{h\left(\cos(h)+1\right)}\right)$$

Egin \cos(h)+1 bider \cos(h)-1.

$$\lim_{h\to 0}\frac{\left(\cos(h)\right)^{2}-1}{h\left(\cos(h)+1\right)}$$

Erabili identitate pitagorikoa.

$$\lim_{h\to 0}-\frac{\left(\sin(h)\right)^{2}}{h\left(\cos(h)+1\right)}$$

Idatzi berriro limitea.

$$\left(\lim_{h\to 0}-\frac{\sin(h)}{h}\right)\left(\lim_{h\to 0}\frac{\sin(h)}{\cos(h)+1}\right)$$

\lim_{x_{2}\to 0}\frac{\sin(x_{2})}{x_{2}} limitea 1 da.

$$-\left(\lim_{h\to 0}\frac{\sin(h)}{\cos(h)+1}\right)$$

Erabili \frac{\sin(h)}{\cos(h)+1} balioaren jarraitutasuna hemen: 0.

$$\left(\lim_{h\to 0}\frac{\sin(h)}{\cos(h)+1}\right)=0$$

Ordezkatu 0 balioa \sin(x_{2})\left(\lim_{h\to 0}\frac{\cos(h)-1}{h}\right)+\cos(x_{2}) adierazpenarekin.

$$\cos(x_{2})$$

Ebaluatu

$$\sin(x_{2})$$
