Question

1. (i) (1 - cos²0) cosec²0 = 1​

Answer 1

Heya Mate ur answer is...

1-cos^2= sin^2

Using this..

sin^2 theta × cosec^2theta = 1(as cosec is the recipocal of sin)

Hope it helps ❤️❤️

Answer 2

As we know that,

=> (1-cos^2Ø) = Sin^2Ø

and

=> Sin^2Ø = 1/Cosec^2Ø

Expression,

= (1-cos^2Ø) Cosec^2Ø

= Sin^2Ø Cosec^2Ø

= 1/Cosec^2Ø x Cosec^2Ø

= 1
