I'm struggling to understand the equations around SHM for M3.
What does n stand for in the equation for the period, T ?
T= 2π/n.
Thanks

The equation is usually written as T= 2π/ω
That is, with ω not n
ω is a constant of the motion.
The usual significance of ω is that it equals the angular velocity of the circular motion that is used to represent SHM.
If a point moves round a circle at angular velocity ω radians per second, and there are 2π radians (360 deg) in one complete circle, then it will take a time of 2π/ω to complete the circle. [Time is distance divided by speed] The time to complete one complete revolution is T, the period of the motion. -
