If `sin A-sqrt6 cos A=sqrt7 cos A`, then `cos A + sqrt6 sin A =`

If sin A- sqrt6 cos A= sqrt7 cosA , then: cosA+ sqrt6 sinA 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-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 is equal

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

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

If sqrt2 cos A = cos B + cos^(3) B "and" sqrt2 sin A = sin B - sin^(3) B, "then the value of" sin (A - B) "will be"

If sin theta-sqrt(6)cos theta=sqrt(7)cos theta. Prove that cos theta+sqrt(6)sin theta-sqrt(7)sin theta=0

If sin theta-sqrt(6)cos theta=sqrt(7)cos theta .Prove that cos theta+sqrt(6)sin theta-sqrt(7)sin theta=0

If sqrt(2)cos A = cos B + cos^(3)B , and sqrt(2)sin A = sin B- sin^(3)B then sin(A-B)=
