Given : \csc \theta+\cot\theta = p

To find : \csc \theta

Step-by-step explanation:

\csc \theta+\cot\theta = p ..(1)\\\\using \\\\\csc^2\theta-\cot^2\theta=1\\\\(\csc \theta+\cot\theta )(\csc \theta-\cot\theta )=1\\\\p + (\csc \theta-\cot\theta )=1\\\\(\csc \theta-\cot\theta )=\frac{1}{p}..(2)\\\\text{add 1 and 2}\\\\2\csc\theta = p+\frac{1}{p}\\\\\text{taking LCM}\\\\2\csc\theta = \frac{p^2+1}{2}\\\\\csc\theta = \frac{p^2+1}{2p}
