Answer 2

Answer:

yes it is easy..

Step-by-step explanation:

sin@ + cosec@ = √3

(squaring both sides.)

(sin@ + cosec @ )² = (√3 )²

sin² @ + cosec²@ +2 sin@ * cosec @ = 3. [sin @ = 1/ cosec@ ]

sin² @ + cosec²@ + sin @* 1/ sin@ = 3

sin² @ + cos² @ = 3-2

sin²@ + cos ² @ = 1 ( Hence , proved )
