Vedclass · Answer

$\cos ec	heta  - \cot 	heta  = 1 \Rightarrow 1 - \cos 	heta  = \sin 	heta $

$\Rightarrow 2 \sin ^{2} \frac{	heta}{2}=2 \sin \frac{	heta}{2} \cos \frac{	heta}{2}$

$\Rightarrow \sin \frac{	heta}{2}\left(\sin \frac{	heta}{2}-\cos \frac{	heta}{2}ight)=0$

$\because \sin \frac{	heta}{2} 
eq 0 \Rightarrow 	an \frac{	heta}{2}=1 \Rightarrow 	heta=\frac{\pi}{2}$
