Question

do this .................​

Answer 1

In this question we rationalize the denominator in order to remove square root.

Taking L.H.S,

= √1+CosØ/1-CosØ

Rationlising the denominator....

= √1+CosØ/1-CosØ × 1+CosØ/1+CosØ

= √(1+CosØ)²/1-Cos²Ø

= √(1+CosØ)²/Sin²Ø

= 1+CosØ/SinØ

= 1/SinØ + CosØ/SinØ

= CosecØ + CotØ
