How to calculate sine period formula w
For sine function f(x)=Asin(ωx+φ), (ω >; 0)

Minimum positive period T=2π/ω

The formula is the one above.

Sine/sine wave is a sine proportional curve in mathematical trigonometric function. It also represents an analog signal, not a square wave representing a digital signal.

Sine curve can be expressed as y=Asin(ωx+φ)+k, and defined as the image of function y=Asin(ωx+φ)+k in rectangular coordinate system, where sin is the sine symbol, x is the value on the X axis of rectangular coordinate system, y is the corresponding y value of this function in the same rectangular coordinate system, and k, ω and φ are constants (k, ω, φ ?).

A sine curve is a wavy line.
