 \sqrt{ \frac{1 - cos \theta}{1 + cos \theta} }  \\  \\  =  \sqrt{ \frac{1 - cos \theta}{1 + cos \theta}  \times  \frac{1 - cos \theta}{1 - cos \theta} }  \\  \\  =  \sqrt{ \frac{( {1 - cos \theta})^{2} }{ {sin}^{2} \theta } }  \\  \\  =   \frac{1 - cos \theta}{sin \theta}  \\  \\  = cosec \theta - cot \theta
