Math help

Idk if this is correct place, but it surely is the more fitting (support at least).

f and g are functions of Domain = R defined respectively by

f(x) = 1 - cos(3x) and g(x) = sin(3x)

a is a real number, belonging to the interval ] pi/3 , pi/2 [

consider r and s such as

r is tangent to the f function graphic, in the point of absciss a
s is tangent to the g function graphic, in the point of abciss a + pi/6

It is known that r and s are perpendicular


Prove that sen(3a) = -(1/3)

I doubt people asked this exact problem, since it comes from an exam from last year.
