`(1)/(1+sin theta ) +(1)/(1-sin theta) = ? `

If (1/(1-sin theta) +1/(1+sin theta)) = 4sec theta , 0^circ lt theta lt 90^circ then the value of (3cot theta + cosec theta) is: यदि (1/(1-sin theta) +1/(1+sin theta)) = 4sec theta , 0^circ lt theta lt 90^circ है, तो (3cot theta + cosec theta) का मान हैः

sqrt((1+sin theta)/(1-sin theta)?)?

If 0 lt theta lt (pi)/(2) and (y+1)/(1-y) =sqrt((1+ sin theta)/( 1- sin theta)), then y is equal to

If 0 lt theta lt (pi)/(2) and (y+1)/(1-y) =sqrt((1+ sin theta)/( 1- sin theta)), then y is equal to

1-(sin^(2) theta)/(1+cos theta) + (1+cos theta)/(sin theta) - (sin theta)/(1-cos theta) - (1)/(sec theta)=

Prove that: sqrt((1+ sin theta)/(1 - sin theta)) - sec theta = sec theta - sqrt((1 -sin theta)/(1 + sin theta))

((sin theta+cos theta-1)/(sin theta-cos theta+1))(1+sin theta) =

If pi/2 < theta < pi, then sqrt((1- sin theta)/(1+ sin theta))+sqrt((1+ sin theta)/(1- sin theta)) is equal to

tan theta= A) (sqrt(1-sin^(2)theta))/(sin theta) , B) (1)/(sec theta) , C) (sin theta)/(sqrt(1-sin^(2)theta)) D) (1)/(sqrt(1+Cot^(2)theta)
