" 1) "cos theta-sin theta=(1)/(sqrt(2))

Solve the following trigonometric equation : cos theta -sin theta=1/sqrt2 .

If 2cos theta - sin theta = 1/sqrt(2), (0^(@) lt theta lt 90^(@)) then the value of 2sin theta + cos theta is:

If cos theta+sin theta=sqrt(2)cos theta then prove that cos theta-sin theta=sqrt(2)sin theta

If cos theta+sin theta=sqrt(2)cos theta, then prove that cos theta-sin theta=sqrt(2)sin theta

If cos theta + sin theta = sqrt(2) cos theta then S.T cos theta - sin theta = sqrt(2) sin theta

If cos theta+sin theta=sqrt(2)cos theta, prove that cos theta-sin theta=sqrt(2)sin theta

If cos theta+sin theta=sqrt(2)cos theta prove that cos theta-sin theta=sqrt(2)sin theta

If cos theta + sin theta = sqrt(2) cos theta , show that cos theta - sin theta = sqrt(2) sin theta .

If cos theta + sin theta =sqrt(2) cos theta prove that cos theta -sin theta =sqrt(2) sin theta

If cos theta+sin theta=sqrt(2)cos theta then show that cos theta-sin theta=sqrt(2)sin theta
