He had read extensively on this topic and he clearly had thought deeply on the works of Newton, Daniel Bernoulli, Taylor, Euler and d'Alembert . Lagrange used a discrete mass model for his vibrating string, which he took to consist of n masses joined by weightless strings.
Niya basahin nang husto sa paksang ito at malinaw na siya ay may-iisip ng matindi sa mga gawa ng Newton, Daniel Bernoulli, Taylor, Euler at d'Alembert. Lagrange na ginagamit ng isang discrete masa modelo para sa kanyang vibrating string, na kung saan siya kinuha na binubuo ng n masa sumali sa pamamagitan ng timbang string.
