The page is part of a section titled \"HISTORY OF ANALYSIS\".\n\n### Text Content Summary\nThe page introduces Gottfried Wilhelm Leibniz, noting his birth and death years (1646-1716). It highlights his significant contribution to mathematics, specifically stating that he independently arrived at the same fundamental concepts of integral and differential calculus as Isaac Newton.

He published his work before Newton, however, in 1686. Archive Photos/Getty Images\n*   **Generative AI Prompt**: A monochromatic, highly detailed engraving of Gottfried Wilhelm Leibniz, a European man from the 17th century. He has a roundish face, a calm expression, and is looking directly at the viewer. He wears a large, curly, dark wig that frames his face and shoulders. His attire consists of a white cravat or jabot and a dark, buttoned coat with intricate decorative patterns or embroidery visible around the collar and chest. The artistic style should be that of a classical engraving, utilizing fine parallel and cross-hatching lines to create depth, shading, and texture. The overall tone should be sepia or dark brown on a light, aged paper background. The portrait is a bust shot, framed within a simple rectangular border, with a vertically lined background behind the subject.","has_visuals":1,"visual_count":1,"visuals":[{"id":37,"page_number":90,"visual_type":"Portrait","caption":"Gottfried Wilhelm Leibniz (1646-1716) reached the same conclusions as did Isaac Newton regarding integral and differential calculus.
