## Example

In this example, we will get the cosine of a value and print it in the console.

### Steps

1. Drag a `button` component into the canvas and open the `Action` tab. Select the `press` event of the button and drag the `Log.write` function to the event flow.
2. Call the function `Math.cos` inside the `Log.write` function.
3. Enter the value to get the cosine of.
