This is answer of your question

Answer 2

Answer:

$cosec {}^{2} Ø = \frac{1}{sin {}^{2} Ø} \\ \: \: \: \: \: \: \: \: \: = \frac{1}{1 - {cos}^{2}Ø} \\ \: \: \: \: \: \: \: \: \: \: = \frac{1}{1 - {cos}^{2}Ø} \times \frac{1 + cos {}^{2}Ø}{1 + {cos}^{2}Ø} \\ \: \: \: \: \: \: \: \: \: \: = \frac{1 + cos {}^{2}Ø}{(1 - cosØ)(1 + cosØ)}$
