Vedclass · Answer

(c) $\frac{{\cos \,{{12}^o} - \sin \,{{12}^o}}}{{\cos \,\,{{12}^o} + \sin \,\,{{12}^o}}} + \frac{{\sin \,\,{{147}^o}}}{{\cos \,\,{{147}^o}}}$

$ = \frac{{1 - 	an \,\,{{12}^o}}}{{1 + 	an \,\,{{12}^o}}} + 	an \,\,{147^o}$

$ = 	an \,\,{33^o} - 	an \,\,{33^o} = 0$.

$\frac{{\cos 12^\circ - \sin 12^\circ }}{{\cos 12^\circ + \sin 12^\circ }} + \frac{{\sin 147^\circ }}{{\cos 147^\circ }} = $
