sqrt((1-sin a)/(1+sin alpha))=?

If alpha in[-pi, pi] such that sqrt((1-sin alpha)/(1+sin alpha))=sec alpha-tan alpha Then

Givent that (pi)/(2)

If pi

(1)/(sqrt(sin^(3)x sin(x+alpha)))

If (2sin alpha) / ({1 + cos alpha + sin alpha}) = y, then ({1-cos alpha + sin alpha}) / (1 + sin alpha) =

If y = (2 sin alpha )/(1 + cos alpha + sin alpha) then, prove that (1 - cos alpha + sin alpha)/(1 + sin alpha) = y .

(1+sqrt(1+a))tan alpha=1+sqrt(1-a)rArr sin4 alpha=
