lower sum
[lower sum|lower sum] are special kinds of Riemann sums where function values are evaluated at left or right endpoints of subintervals.
Definition
lower sum are special kinds of Riemann sums where function values are evaluated at left or right endpoints of subintervals. These approximations provide flexibility in calculating lower or upper bounds for integrals.
Effects
lower sum affects the integration of functions resulting from a chain-rule derivative. Substitution simplifies this process as a technique.
Examples
lower sum In this case, the associated Riemann sum is called a lower sum.
