" If "sin A+cos A=sqrt(2)cos A," show that "cos A-sin A=sqrt(2)sin A

sin x + cos x = sqrt (2) cos A

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

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

If sin A - sqrt(6) cos A = sqrt(7) cos A , then cos A + sqrt(6) sin A is equal

If sin x + cos x =sqrt2 cos x , show that : sqrt2 sin x =cos x- sin x .

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

If "sin" x + "sin"^(2) x = 1 show that: cos^(4)x + cos^(2)x = 1 (ii) If "sin" x + cos x =sqrt(2) cos x show that: sqrt2 sin x = cos x - sin x

If sin A-sqrt(6)cos A=sqrt(7)cos A, then cos A+sqrt(6)sin A is equal to

If sin A-sqrt(6)cos A=sqrt(7)cos A, then cos A+sqrt(6)sin A equal to

If sin A-sqrt6 cos A = sqrt7 cos A , " then " cos A + sqrt6 sin A is equal to
