Michel de l'Hôpital

Michel de l'Hôpital was a French mathematician and a prominent figure in the 16th century, known for his work in calculus. He is best remembered for L'Hôpital's Rule, a method used to evaluate limits in mathematics, particularly when direct substitution leads to indeterminate forms. His rule provides a systematic way to find limits involving fractions by differentiating the numerator and denominator. L'Hôpital's contributions significantly advanced the understanding of calculus and inspired further mathematical exploration, making complex calculus problems more approachable for students and mathematicians alike.
