Tan theta + sin theta =m ,tan theta -sin theta =n this is actual qstnm square and n square can be written as (m+n) (m-n)
so we can write as (tan theata +sintheata+(tan theata -sintheata))(tan theata +sintheata-(tan theata -sin theata))
we wrte it as(tan theata +sintheata+tan theata -sintheata))(tan theata +sintheata-tan theata +sin theata))
on simplyfying we get it as
(tan theata +tan theata)(+sint theata  +sin theata)
(2tan theata)(2sintheata)
4tan theata. sin theata or 4(tan theata sin theata)
