If `x=(sqrt(1-sin4theta)+1)/(sqrt(1+sin4theta)-1` then one of the values of `x` is

4sin 4theta +1=sqrt(5)

If y=(sqrt(1-sin4x)+1)/(sqrt(1+sin 4x)-1) , then y can be

If y=(sqrt(1-sin4x)+1)/(sqrt(1+sin 4x)-1) , then y can be

If y=(sqrt(1-sin4x)+1)/(sqrt(1+sin 4x)-1) , then y can be

4sin 4theta -1 = sqrt(5)

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

If 0<=theta<=pi and (sin0)/(2)=sqrt(1+sin theta)-sqrt(1-sin theta) then the possible value of tan theta, is -

Evaluate: sqrt((1-sin theta)/(1+sin theta)) .
