$\cos 35^{\circ} = \ldots \ldots \ldots$

यदि $\cos A = \frac{4}{5}$ है,तो $\tan A$ का मान ज्ञात कीजिए।

यदि $5 \cos A = 4 \sin A$,तो $\tan A = \ldots$

यदि $\sec \theta = \frac{5}{3}$ है,तो $\tan \theta = \ldots$

$\tan (65^\circ - \theta) - \cot (25^\circ + \theta) - \sec (55^\circ - \theta) + \operatorname{cosec}(35^\circ + \theta) = \ldots \ldots \ldots \ldots$ (जहाँ,$0 < \theta < 25^\circ$)

$\sin \theta \cdot \cos (90^\circ - \theta) = \ldots \ldots \ldots$
