# InvSinWave 📅🅕🅝
## Documentation
- Class name: `InvSinWave`
- Category: `FizzNodes 📅🅕🅝/WaveNodes`
- Output node: `False`

The InvSinWave node generates an inverse sine wave pattern, modifying the wave's amplitude based on the absolute value of the cosine function. It's designed for creating dynamic, wave-like animations or effects by adjusting parameters such as phase, amplitude, x translation, and y translation over a series of frames.
## Input types
### Required
- **`phase`**
    - Defines the period of the wave, affecting how many units it takes for the wave to complete one full cycle. A crucial parameter for controlling the wave's speed and spacing.
    - Comfy dtype: `FLOAT`
    - Python dtype: `float`
- **`amplitude`**
    - Determines the height of the wave's peaks. This parameter influences the wave's intensity and the range of its vertical movement.
    - Comfy dtype: `FLOAT`
    - Python dtype: `float`
- **`x_translation`**
    - Shifts the wave along the x-axis, allowing for horizontal positioning adjustments.
    - Comfy dtype: `FLOAT`
    - Python dtype: `float`
- **`y_translation`**
    - Adjusts the wave's vertical positioning, allowing for vertical positioning adjustments.
    - Comfy dtype: `FLOAT`
    - Python dtype: `float`
- **`current_frame`**
    - Specifies the current frame in the animation sequence, enabling the wave pattern to evolve over time.
    - Comfy dtype: `INT`
    - Python dtype: `int`
## Output types
- **`float`**
    - Comfy dtype: `FLOAT`
    - Outputs the calculated wave value, useful for precise wave calculations.
    - Python dtype: `float`
- **`int`**
    - Comfy dtype: `INT`
    - Outputs the integer representation of the wave value, useful for scenarios requiring discrete values.
    - Python dtype: `int`
## Usage tips
- Infra type: `CPU`
- Common nodes: unknown
