" 4.if "sin theta+cos theta=1" then the value of "sin2 theta" is equal to "

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 cos theta+sqrt3 sin theta=2 , then the value of theta is equal to

If sin theta+cos theta=1, then sin theta cos theta is equal to :

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

If cos theta + sin theta = sqrt2 cos theta " then" cos theta - sin theta is equal to

If cos theta + sin theta = sqrt2 cos theta " then" cos theta - sin theta is equal to

If 2 cos theta + sin theta =1 then 7 cos theta + 6 sin theta is equal to

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

If sin theta = cos theta ,then the value of 2 tan^(2) theta + sin^(2) theta -1 is equal to
