(B) આપણે લક્ષ્યની કિંમત શોધવાની છે: $\mathop {\lim }\limits_{	heta 	o 0} \frac{{\sin 3	heta - \sin 	heta }}{{\sin 	heta }}$$\sin 3	heta = 3\sin 	heta - 4\sin^3 	heta$ સૂત્રનો ઉપયોગ કરતા:$= \mathop {\lim }\limits_{	heta 	o 0} \frac{{(3\sin 	heta - 4\sin^3 	heta) - \sin 	heta }}{{\sin 	heta }}$$= \mathop {\lim }\limits_{	heta 	o 0} \frac{{2\sin 	heta - 4\sin^3 	heta }}{{\sin 	heta }}$$= \mathop {\lim }\limits_{	heta 	o 0} (2 - 4\sin^2 	heta)$$= 2 - 4(0)^2 = 2$વૈકલ્પિક રીતે,$\mathop {\lim }\limits_{	heta 	o 0} \frac{{\sin n	heta }}{{\sin 	heta }} = n$ ગુણધર્મનો ઉપયોગ કરતા:$= \mathop {\lim }\limits_{	heta 	o 0} \frac{{\sin 3	heta }}{{\sin 	heta }} - \mathop {\lim }\limits_{	heta 	o 0} \frac{{\sin 	heta }}{{\sin 	heta }}$$= 3 - 1 = 2$

$\mathop {\lim }\limits_{\theta \to 0} \frac{{\sin 3\theta - \sin \theta }}{{\sin \theta }} = $
