Derivatives question

[Neddo]

I always struggled to understand these relations.

dx/dt= Aωcos(ωt+φ)
dV/dt= d^2 x/dt^2= Aω^2cos(ωt+φ)

how do these derivate?

I just got my anwser, anyways.

These are harmonyc oscillation formulas for speed and acceleration.

Thank you for taking your time.

Aωcos(ωt+φ)

I think this roughly translate to hood speak as "Aw, cuz, what up?"
