Whakaoti i te sin(θ_{1})=

$$\sin ( \theta _ { 1 } ) =$$

Kimi Pārōnaki e ai ki θ_1

$$\cos(\theta _{1})$$

Ngā Upane e Whakamahi ana i te Tautuhinga o te Pārōnaki

Mō tētahi pānga f\left(x\right), ko te pārōnaki te tepe o \frac{f\left(x+h\right)-f\left(x\right)}{h} ina haere h ki 0, mēnā kei reira taua tepe.

$$\frac{\mathrm{d}}{\mathrm{d}\theta _{1}}(\sin(\theta _{1}))=\left(\lim_{h\to 0}\frac{\sin(\theta _{1}+h)-\sin(\theta _{1})}{h}\right)$$

Whakamahia te Tikanga Tātai Tapeke mō te Aho.

$$\lim_{h\to 0}\frac{\sin(h+\theta _{1})-\sin(\theta _{1})}{h}$$

Tauwehea te \sin(\theta _{1}).

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

Tuhia anō te tepe.

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

Whakamahia te meka ko \theta _{1} he pūmau ina tātai tepe i te wā ka haere h ki te 0.

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

Ko te tepe \lim_{\theta _{1}\to 0}\frac{\sin(\theta _{1})}{\theta _{1}} he 1.

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

Hei arotake i te tepe \lim_{h\to 0}\frac{\cos(h)-1}{h}, tuatahi me whakarea te taurunga me te tauraro ki te \cos(h)+1.

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

Whakareatia \cos(h)+1 ki te \cos(h)-1.

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

Whakamahia te Tuakiri Pythagorean.

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

Tuhia anō te tepe.

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

Ko te tepe \lim_{\theta _{1}\to 0}\frac{\sin(\theta _{1})}{\theta _{1}} he 1.

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

Whakamahia te meka he motukore a \frac{\sin(h)}{\cos(h)+1} i 0.

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

Whakakapihia te uara 0 ki roto i te kīanga \sin(\theta _{1})\left(\lim_{h\to 0}\frac{\cos(h)-1}{h}\right)+\cos(\theta _{1}).

$$\cos(\theta _{1})$$

Aromātai

$$\sin(\theta _{1})$$
