If sin theta+cos theta=1 then the value of sin 2 theta is equal to

If sin theta + cos theta =1, the value of sin theta cos theta is

If sin theta + sin^2 theta =1 , then the value of cos^2 theta + cos^ 4 theta is

If x=(2 sin theta)/(1+ sin theta + cos theta) then the value of (1+ sin theta - cos theta)/(1+ sin theta)

If cos theta + sin theta =sqrt2 cos theta , then the value of (cos theta -sin theta)/(sin theta) is

If (sin theta + cos theta)/(sin theta - cos theta)=3 , then the value of sin^(4)theta - cos^(4)theta is:

if sin theta-cos theta=(1)/(2) then the value of (1)/(sin theta+cos theta)

If (cos theta)/(1+sin theta)-(1-sin theta)/(cos theta)=2k then the value of k is :

If sin theta_1 + sintheta_2 + sin theta_3=3, then find the value of cos theta_1 + cos theta_2 + cos theta_3.
