The principal value of `(theta+pi/4)` where value of `sintheta+ costheta =1 ` is

If sintheta + cos theta =1 , then the value of sintheta - costheta is:

If sin theta - cos theta =1/29 find the value of sintheta + costheta .

I : Principal value of cos theta = -1 is pi II : Principal value of sin theta = 0 is pi

A value of theta satifying 4costheta sintheta - 2sintheta =0 is

A value of theta satifying 4costheta sintheta - 2sintheta =0 is

If sin theta-cos theta=(1)/(2) ,then find the value of sintheta+costheta

if sintheta-costheta=0, then the value of (sin^4theta+cos^4theta)

For ____value of theta , sintheta+costheta=sqrt2

For what value of theta , where 0 lt theta lt pi/2 does sintheta + sintheta.costheta attain maximum value?

If Sintheta=costheta , find the value of theta
