Inverted sinus and cosinus in docs

[PauSala]

Hello!
It is possibel that here
the sinus and cosinus are inverted for some reason while calculating the coordinates?

    // Get the sine of the radian to find the x co-ordinate of this point of the circle
    // and multiply it by the radius.
    let x = radian.sin() * radius;
    // Do the same with cosine to find the y co-ordinate.
    let y = radian.cos() * radius;
    // Construct and return a point object with a color.

Thank you!
