If `sin theta +cos theta =sqrt2` , then the principal value of `(theta +pi/4 )` is

If sin theta + cos theta = sqrt2 , then find the value of theta .

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

If sin theta cos theta = sqrt3//4 ,then the value of sin^4theta + cos^4 theta is

If sin theta cos theta=sqrt(2)cos theta then the value of sin theta+cos theta is

If sin(pi cos theta) = cos(pi sin theta) , then of the value cos(theta- pi/4) is

If 4 sin^2 theta + 2(sqrt3 + 1) cos theta = 4 + sqrt3 then the general value of theta is

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

If 4sin^(2)theta+2(sqrt(3)+1)cos theta=4+sqrt(3) then the general value of theta is

If sec theta ( cos theta + sin theta) = sqrt""2 , then what is the value of (2 sin theta )// (cos theta - sin theta ) ?
