Question

If sin α+ cosec α=2 then find sinα+cosecnαif sin α+ cosec α=2 then find sinα+cosecnα

Answer 1

here α =π|2 and there fore sinα+cosec nα = 1+cosecnπ|2 , the value depends on  n
if n is even the value is nt defined if n is odd  i e n=(2m+1)π|2 here if m is even answer is 2  if m is odd answer is 0
