Let `P={theta:sintheta-costheta=sqrt2costheta}and Q={theta: sintheta+costheta=sqrt2sintheta}` be two sets. Then

Let P = [theta : sintheta – costheta = sqrt2 costheta) andQ= {theta : sintheta + costheta = 12 sintheta} be two sets. Then:

If costheta+sintheta=sqrt(2)costheta, show that costheta-sintheta=sqrt(2)sintheta

If costheta+sintheta=sqrt(2)costheta, show that costheta-sintheta=sqrt(2)sintheta

If costheta+sintheta=sqrt(2)costheta, show that costheta-sintheta=sqrt(2)sintheta

If costheta+sintheta=sqrt(2)costheta, show that costheta-sintheta=sqrt(2)sintheta

If sintheta+costheta=sqrt(2)cos(90o-theta) , find cottheta .

If costheta-sintheta=sqrt(2)sintheta , then prove that: costheta+sintheta=sqrt(2)costheta

If sintheta + 2 costheta=1 ,then prove that 2sintheta-costheta=2 .

If cos theta-4sintheta=1, the sintheta+4costheta=

If sintheta+costheta=sqrt(2)sin(90^@-theta) , determine cottheta .
