SUMMARY

The discussion clarifies that "dx" in integrals represents the variable of integration, specifically indicating the infinitesimally small interval over which the function is summed. This concept is rooted in Riemann sums, where the integral is defined as the limit of the sum of function values multiplied by these infinitesimal intervals. Understanding "dx" is essential for grasping the fundamental principles of calculus and integration.

PREREQUISITES
  • Understanding of Riemann sums
  • Basic knowledge of calculus
  • Familiarity with the concept of limits
  • Ability to interpret mathematical notation
NEXT STEPS
  • Study the definition and properties of Riemann integrals
  • Learn about the Fundamental Theorem of Calculus
  • Explore the concept of limits in calculus
  • Investigate applications of integrals in real-world scenarios
USEFUL FOR

Students of calculus, mathematics educators, and anyone seeking to deepen their understanding of integration and its foundational concepts.

that x is the variable that you perform the integral over. Variable of integration.

It comes from the definition of integral, that you sum over the function value multiplying it with a very very small x-intervall (length multiplied with height). Riemann summary. If we make the intervall infinitesimal (dx), the we have to do, in practice, an infinite amount of summations over these "function value" * "length of intervall"
