Minimum positive period: 2π/w

In the trigonometric function model, we will encounter the trigonometric function image y=Asin(ωx+φ). Physical quantities describing simple harmonic vibration in physics, such as amplitude, period and frequency, are all related to the constants in this analytical formula.

A is the amplitude of simple harmonic motion, which is the maximum distance from the equilibrium position of an object that is simple harmonic motion;

The period of this simple harmonic vibration is T=2π/ω, which is the time required for an intermittent object to reciprocate once;

The frequency of this simple harmonic vibration is given by the formula f =1/t = | Ω |/2π (the frequency here does not refer to angular velocity), which is the number of times the object doing intermittent motion reciprocates in unit time;

The amplitude of this simple harmonic vibration is a.

ωx+φ is called phase.

The phase (ωx+φ=φ) when x=0 is called the initial phase, (the premise of the initial phase is (a >；; 0，ω& gt； 0), if one of them is not, it can be transformed by inductive formula to meet the above conditions. )
