   I have this formula in my book:
   [tex] \[ a = - \omega x^{2} \] [/tex]
   Can anyone help me show how to show that this formula is true?

   What does that formula relate to?
   
   If it is supposed to relate to SHM then the equation is supposed to be [itex]a=- \omega^2 x[/itex]

   yes sorry, that was what i meant. Do you know how to show the formula from the equations of motion?

   The equation of motion is:
   
   [tex]
   m a = - k x
   [/tex]
   
   What is the definition of [itex]\omega[/itex]? Then solve the equation of motion for a.
