How do you know if a phase shift is positive or negative?
The phase shift of a sine curve is how much the curve shifts from zero. If the phase shift is zero, the curve starts at the origin, but it can move left or right depending on the phase shift. A negative phase shift indicates a movement to the right, and a positive phase shift indicates movement to the left.
What is phase shift in trigonometry?
When we move our sine or cosine function left or right along the x-axis, we are creating a Horizontal Shift or Horizontal Translation. In trigonometry, this Horizontal shift is most commonly referred to as the Phase Shift. As Khan Academy states, a phase shift is any change that occurs in the phase of one quantity.

The phase shift of a sine curve is how much the curve shifts from zero. If the phase shift is zero, the curve starts at the origin, but it can move left or right depending on the phase shift. A negative phase shift indicates a movement to the right, and a positive phase shift indicates movement to the left.

Since is being added inside the parentheses, there will be a horizontal shift. The goal is to maintain zero within the parentheses so you will shift left radians.
What is phase shift?
Generally, the phase shift is the x-distance between (0.0, 0.0) and the next zero-crossing to the left, given in an angle, usually in radian, sometimes also given in degree. In high school mathematics, the assumption is that the phase shift is simply the same as the horizontal shift.

Because the shift is to the right, or later in time, we can say the signal lags (or is behind) the unshifted signal one tenth of a cycle, or 36°.
How many milliseconds is a horizontal shift?
In signal analysis it's convenient to measure horizontal shift in both absolute terms, i.e. a shift of 3 milli seconds to the right, (in many applications time is the horizontal axis), but also in terms of the number of cycles you have shifted. One cycle is considered to be 360° or 2π radians.-
Is 360° phase shift a shift?
A 360° phase shift is no shift at all.
Is phase shift the same as horizontal shift?
In high school mathematics, the assumption is that the phase shift is simply the same as the horizontal shift. This in many ways renders the concept of phase shift as something distinct from horizontal shift meaningless.

What is phase shift formula?
We know that in the phase shift formulas A * sin (Bx - C) + D and A * cos (Bx - C) + D, the A determines how far the values fluctuate on either side of the centerline.

Also, together with C, the two describe if we've moved the function to the left or right and how much.

Therefore, the only thing that can affect the amplitude in the phase shift formulas A * sin (Bx - C) + D and A * cos (Bx - C) + D is the non-zero A. And indeed, since sin (Bx - C) and cos (Bx - C) are all this time between -1 and 1, the multiplier A changes this range to -1 * A = -A and 1 * A = A.
What is phase shift?
The phase shift (also called the horizontal shift or horizontal translation) describes how far horizontally the graph has been moved from the regular sine or cosine. As such, the value is equal to 0 if we have the two functions unaltered.
What is the amplitude of a graph?
The amplitude is how far (either way) the values run from the graph's centerline. For a simple sine or cosine, its value is 1 since the centerline is at 0, and the function's values range from -1 to 1.
What is the period of a graph?
The period is the length on the horizontal axis, after which the function begins repeating itself. In other words, the (infinite) graph is just a bunch of period-length copies glued together at the ends. For a simple sine or cosine, the period equals 2π since sin (0) = sin (2π) = sin (4π) = ... and the parts in between are exactly the same (and similarly for the cosine).

Positive, the graph is shifted to the right.

Divide the initial position by the initial velocity. Remember that frequency is determined by the spring constant and mass, so phase angle is related to the ratio of initial position to initial velocity.
