1. Answer:

   cosec theeta ×√(1-cos^2theeta)

   =cosec theeta×√sin^2theeta

   =cosec theeta ×sin the eta

   =1/sin theeta×sin theeta

   =1=RHS

2. [tex]cosec \theta \sqrt{1 – {cos}^{2} \theta } \\ = cosec \theta \sqrt{ {sin}^{2} \theta} \\ = cosec \theta \: sin \theta \\ = cosec \theta \: \frac{1}{cosec \theta} \\ = 1[/tex]
