    The axis of sinusoidal symmetry is x=k + 2 and k is an integer.

    Addendum: The sinusoidal curve can be expressed as y=asin(x+)k, which is defined as the image of the function y=asin(x+)k in a Cartesian coordinate system, where sin is the sinusoidal symbol, x is the value on the x-axis of the Cartesian coordinate system, y is the value of the function corresponding to the function in the same Cartesian coordinate system, and k, and are constants (k, , r, and ≠0).

    When the waveform moves, it should be noted that the amplitude a becomes larger, and the difference between the maximum and minimum values of the waveform on the y-axis becomes larger; If the amplitude a decreases, the opposite is true; When the angular velocity increases, the waveform shrinks on the x-axis (the waveform becomes compact); The angular velocity decreases, and the waveform spreads on the x-axis (the waveform becomes sparse). Another point is that if you want to move the waveform to the left or right if you want to move y=asin( x+ )) to the left, then it should be changed to this form of the formula y=asin[ (x+ ))] if you want to move the m angle to the right, it becomes y=asin[ (x+ -m)], and vice versa, if you move to the left, it becomes y=asin[ (x+ +m)].

    The axis of symmetry of the sinusoidal function refers to which line the image is symmetrical about. For a sinusoidal function, it has two axes of symmetry:

    Axis: The sinusoidal function y = sin(x) is based on the x-axis as the axis of symmetry. This means that points that are symmetrical above and below the x-axis have the same function value.

    For example, when x = 0, y = sin(0) =0, and when x = , y = sin( )0, this indicates that the image has symmetry on the x-axis.

    2.Perpendicular line: The sinusoidal function also has symmetry with respect to the perpendicular line leakage x = k (k is an integer).

    This means that in each full or half period, the image of the sinusoidal function is symmetrical in the positions of the vertical line x = k and the vertical line x = k + 1 2). Specifically, when x = k, y = sin(k) 0, and when x = k + 1 2), y = sin((k + 1 2))1, which shows that the function image is symmetrical on these two vertical comma lines.

    These symmetries can be used to simplify the image drawing and property analysis of sinusoidal functions. They show the repetitive and periodic properties of the sine function and can help us understand how the sine function changes across the defined domain.

    The sine function takes the maximum or minimum value on the axis of symmetry, and the axis of symmetry of the sine function is:

    y-axis (x=0);

    All straight lines parallel to the y-axis;

    All lines parallel to the x-axis.

    Specifically, the axis of symmetry of the sinusoidal function sin(x) is x=k and k is an integer. This is because the sinusoidal function takes the maximum or minimum value of the circular brigade at this point. If we translate the sinusoidal function to the left or right k before the Hui Zhou Hui cavity answer period, it still takes the maximum or minimum value on the axis of symmetry.

    Also, the value of the sinusoidal function on the axis of symmetry is 0 or earth 1. If we translate the sinusoidal function to the left or right for n periods, it still takes 0 or earth 1 on the axis of symmetry.

    Thus, the axis of symmetry of a sinusoidal function has the y-axis and all the lines parallel to the y-axis, and all the lines parallel to the x-axis.

    1.Vertical axis of symmetry: The axis of symmetry of the sinusoidal function y = sin(x) is the straight core line x = 2 or x = 2.

    This means that for any x, the values of the functions of y = sin(x) and y = sin(-x) are equal.

    2.Horizontal axis of symmetry: The axis of horizontal symmetry of the sinusoidal function y = sin(x) is the x-axis (y = 0). This means that when x is positive or negative, the corresponding function value is symmetrical with respect to the x-axis.

    The symmetry of the sinusoidal function makes it have important applications in mathematics and physics.
