Create a professional textbook cover image for the book with the title "Calculus"

Aspect ratio: 1.91:1 (1200x630 pixels) for social media Open Graph compatibility.

Please the title "Calculus" in the center of the image in title case using a gold color.

Style: Modern, clean, educational, inspiring. Professional academic aesthetic with a sense of discovery and intellectual achievement.

Visual elements to include as a subtle montage background:
- Calculus curves and function graphs (sine waves, parabolas, exponential curves)
- Derivative notation (dy/dx, f'(x)) floating subtly
- Integration symbols (∫) elegantly placed
- Tangent lines touching curves
- Area under curves (shaded regions)
- Limit notation (lim as x approaches)
- Coordinate axes with smooth curves
- Newton and Leibniz era scientific instruments subtly referenced
- Abstract representations of motion and change

Color palette: Deep purple primary (matching MkDocs Material theme), with accents of gold, white, and soft
blue. Mathematical elements in lighter tones against darker background.

Composition: Central focus area for title text overlay, with mathematical elements arranged in an aesthetically pleasing pattern around the edges. The design should feel dynamic yet balanced, representing the beauty of
calculus.

Mood: Intellectual, inspiring, accessible. Should appeal to high school and college students while conveying
mathematical sophistication.
