Riemann Sum ஐ எப்படி கணக்கிடுவது

Riemann Sum என்றால் என்ன?

A Riemann sum is a finite approximation of a definite integral. It partitions the interval [a, b] into n subintervals and approximates the area under the curve using n rectangles. As n → ∞, the Riemann sum converges to the exact integral. Riemann sums are the conceptual foundation for understanding what integration means geometrically.

சூத்திரம்

Divide [a, b] into n equal subintervals of width Δx = (b−a)/n

படிப்படியான வழிகாட்டி

  1. 1Divide [a, b] into n equal subintervals of width Δx = (b−a)/n
  2. 2Left Riemann: use left endpoint of each subinterval — Σ f(xᵢ) · Δx
  3. 3Right Riemann: use right endpoint — Σ f(xᵢ₊₁) · Δx
  4. 4Midpoint Riemann: use midpoint — Σ f((xᵢ+xᵢ₊₁)/2) · Δx
  5. 5Midpoint rule is generally more accurate than left or right for the same n
