Create a clean educational math infographic about [CALCULUS TOPIC], designed as a helpful AP Calculus study sheet. The final image should look like a polished hand-drawn classroom poster with readable formulas, rule cards, examples, graph sketches, and a quick checklist.

Canvas: 3:2 horizontal layout on a bright off-white paper background. Use dark blue handwritten headline lettering, neat black body text, soft colored section cards, simple icons, small doodles, and generous spacing.

Main headline: "[TOPIC TITLE]". Add one short subtitle that explains the learning goal in plain English. Place a small goal box in the top-right corner.

Content structure: create four large numbered concept cards across the main body. Each card should include a rule name, one sentence explanation, a formula box, one small graph or visual intuition sketch, and one worked example. Use color-coded cards such as blue, teal, yellow, and red.

Bottom section: add a summary table, common mistakes box, special cases note, and quick checklist. Include checkmarks, arrows, small magnifier icon, target icon, and friendly practice reminder.

Readability: formulas must be large enough to read. Keep labels short. Use accurate math notation where possible, but prioritize clear visual hierarchy and student comprehension.

Style: AI calculus limits infographic prompt example, study guide poster, hand-drawn marker notes, clean educational design, friendly AP Calculus classroom aesthetic, high information clarity, no clutter.
