## How does period affect sine graph?

Each period of the graph finishes at twice the speed. You can make the graph of a trig function move faster or slower with different constants: Positive values of period greater than 1 make the graph repeat itself more and more frequently. You see this rule in the example of f(x).

## How do you find the period of a sine graph?

The period of the sine curve is the length of one cycle of the curve. The natural period of the sine curve is 2π. So, a coefficient of b=1 is equivalent to a period of 2π. To get the period of the sine curve for any coefficient b, just divide 2π by the coefficient b to get the new period of the curve.

## What is a period in sine function?

The period of a trigonometry function is the extent of input values it takes for the function to run through all the possible values and start all over again in the same place to repeat the process. In the case of the function y = sin x, the period is 2π, or 360 degrees.

## How many periods are there in Sinx?

two periods
The period of sinx is 2π, whereas period of sinx/2 is 4π. The function f(x), therefore, repeats after 4π, which is equal to LCM of (least common multiplier) of the two periods. It is evident from the graph also. Graphs of sine functions Two functions repeat values after 4π.

## Does a sine graph always start at 0?

The Sine Function has this beautiful up-down curve (which repeats every 2π radians, or 360°). It starts at 0, heads up to 1 by π/2 radians (90°) and then heads down to −1.

## What is the period of y sin 3x?

2π/3
We know that the period of sin x is 2π, therefore the period of sin 3x is 2π/3. This implies the cycle of sin 3x repeats itself after every 2π/3 radians.

## What is the period of Sinx 2?

π
sin2θ=12(1−cos(2θ)) so has period π .

## What are the 5 key points when you graph the sine function?

They are the three x-intercepts, the maximum point, and the minimum point. All of these are on your unit circle. The values of sin x correspond to the y-values, so those key points are (angle, y-value) or (0,0), (π/2, 1), (π, 0), (3π/2, -1), (2π, 0).

## How do you find the period of a sine function?

The period of the sine function is 2π. For instance, sin(π) = 0. If you add 2π to the x-value, you get sin(π + 2π), which is sin(3π).

## How do you calculate the period of a graph?

To find the period of f(x) = sin 2x, and solve for the period. In this case, Each period of the graph finishes at twice the speed. You can make the graph of a trig function move faster or slower with different constants: Positive values of period greater than 1 make the graph repeat itself more and more frequently.

## How do you calculate the period of a sine wave?

The cycle repeats itself in a uniform pattern. The time period of oscillation of a wave is defined as the time taken by any element of the string to complete one such oscillation. For a sine wave represented by the equation: y (0, t) = -a sin (ωt)

## How do you find the period of sin?

The period of your sin function can be found observing the number multiplying the x in the argument: in this case the argument of the sin is: (4x−2) so that the important number will be 4. Try using the x positions two consecutive peaks and see if their spacing is π 2.
