SOLUTION: help verifying this identity please? sin (x + pi/6)

SOLUTION: help verifying this identity please? sin (x + pi/6) - cos (x + pi/3) = sqrt of 3 sin x

Question 916900: help verifying this identity please?
sin (x + pi/6) - cos (x + pi/3) = sqrt of 3 sin x

Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
sin (x + pi/6) - cos (x + pi/3) = sqrt of 3 sin x
-----------------
sin(x)*cos(pi/6) + cos(x)(sin(pi/6) - cos(x)cos(pi/3)-sin(x)sin(pi/3) = sqrt(3)sin(x)
-------
sin(x)(sqrt(3)/2))+ cos(x)(1/2) -[cos(x)(1/2)- sin(x)(sqrt(3)/2)] = sqrt(3)sin(x)
----------------
2[sqrt(3)/2]sin(x) = sqrt(3)sin(x)
----
sqrt(3)sin(x) = sqrt(3)sin(x)
-------------------
Cheers,
