Vedclass · Answer

(D) $(a) \sin 120^{\circ} = \sin(180^{\circ} - 60^{\circ}) = \sin 60^{\circ} = \frac{\sqrt{3}}{2}$$(b) \cos 930^{\circ} = \cos(2 	imes 360^{\circ} + 210^{\circ}) = \cos 210^{\circ} = \cos(180^{\circ} + 30^{\circ}) = -\cos 30^{\circ} = -\frac{\sqrt{3}}{2}$$(c) 	an 840^{\circ} = 	an(2 	imes 360^{\circ} + 120^{\circ}) = 	an 120^{\circ} = 	an(180^{\circ} - 60^{\circ}) = -	an 60^{\circ} = -\sqrt{3}$$(d) \cot(-1110^{\circ}) = -\cot(1110^{\circ}) = -\cot(3 	imes 360^{\circ} + 30^{\circ}) = -\cot 30^{\circ} = -\sqrt{3}$Comparing the values,$(c)$ and $(d)$ both equal $-\sqrt{3}$.

Which of the following have the same value?
$(a)$ $\sin 120^{\circ}$
$(b)$ $\cos 930^{\circ}$
$(c)$ $\tan 840^{\circ}$
$(d)$ $\cot (-1110^{\circ})$
