Create a vibrant and engaging book cover for a mathematics textbook featuring augmented reality content. The central character and presenter is a friendly capybara wearing a captain's hat, standing proudly as if guiding students through the world of math. The capybara should look intelligent, approachable, and a bit whimsical. The background should blend digital and educational elements, such as floating numbers, geometric shapes, and AR holograms, all set in a futuristic or tech-inspired classroom. The title area should be clearly visible, leaving space for the book's name and subtitle. The overall style should appeal to middle and high school students — colorful, modern, and imaginative.
