If `sin theta +cos theta+1=0`, then find `theta`.

If sin theta-cos theta=0 then find the value of sin^6theta+cos^6theta

If sin theta-cos theta=0 then find the value of theta

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

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

If sin theta+cos theta=1 then sin theta cos theta=

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

If (cos theta)/(1- sin theta) + (cos theta)/(1 + sin theta) =4 , then find the value of cos theta . Find theta if 0^(@) lt theta lt 90^(@)

If sin theta+cos theta=0 and theta lies in the fourth quadrant,find sin theta and cos theta

If f(theta)=[(cos theta, -sin theta,0),(sin theta, cos theta, 0),(0,0,1)] then {f(theta)^(-1)} is equal to
