Question

1+cosecA cos^2A
________ =_______
cosec A 1 - sin A

Solution:- Taking the L.H.S.
1+cosec A
________
cosec A
=> 1+ 1 /sinA
___________
1/sinA
=> sin A +1

Taking the R.H.S.
cos^A
_________
1 - sinA

=> 1 -sin^2A
___________ => (1 + sin A)(1 - sin A)
_______________
1 - sinA ( 1 - sinA)

=> sin A+1
So,
L.H.S. = R.H.S.(proved)​

Answer 1

Answer:

This is already proved know.
