Homework Statement
I am trying to derive the formula for simple harmonic motion of a mass hanging on a spring.
I understand the derivation for the situation when the mass and the spring are on an horizontal table. Then I go about deriving the same formula for the situation when a mass is hanging on a spring and I can't seem to get rid of the gravitational force components (F=m*g).

The Attempt at a Solution
I'm very stuck.
I know you guys aren't supposed to hand out answers but this is a matter of understanding the fundamental I would really like a good explanation.
Thanks in advance!
