Description: A complex plane diagram showing the real and imaginary axes with a unit circle. Text labels indicate 'Re', 'Im', 'cos 0', 'sin 0', '1', '0', 'σ', and 'i'. An equation 'e^(iπ) + 1 = 0' is displayed prominently below the diagram, and another equation 'e^(iπ) – cos 0 + i sin 0' is at the top. The style is monochrome and geometric.
Description: A simple white line drawing of a right triangle with a square symbol indicating the right angle. Below the triangle, in a stylized script font, are three equations: "without you = cos 90°", "me and you = sin 90°", and "beside you = tan 90°". The text is white with a faint pink outline.
