Spirograph Equations

The position of the pen point (x, y) on the paper or canvas is determined by trigonometric equations.

The x-coordinate (horizontal position) of the pen point is given by the equation: x = (R - r) * cos(θ) + d * cos(((R - r) / r) * θ)

The y-coordinate (vertical position) of the pen point is given by the equation: y = (R - r) * sin(θ) - d * sin(((R - r) / r) * θ)

Drawing the Spirograph

To create the Spirograph pattern, you start with an initial angle (θ).

You calculate the x and y coordinates of the pen point using the equations mentioned above.

You draw a point or a small shape (such as a circle) at this (x, y) position on the paper or canvas.

You increment the angle (θ) by a small amount (e.g., 0.01 radians) and repeat the process.

By continuously calculating the coordinates and drawing, the pen point traces a path on the canvas, creating the Spirograph pattern.
