Hi beautiful
Here is solution
I have solved earlier so it's degree are A and B
Okey
1 ) cotA + cot B
= cosA/ sinA + cosB/sinB
= ( SinBcosA + cosBsinA )/(sinAsinB)
= sin( A+ B ) / sinA sinB
= cosecAcosecB/Cosec( A + B )--( 1 )
Now ,
RHS =( cosecAcosecB)/(cotA+cotB)
=(cosecAcosecB)/[(cosecAcosecB)/Cosec(A+B )]
[ From ( 1 ) ]
= Cosec( A+ B )
= LHS
Hence proved.
I hope this helps you.
