The LRAM, RRAM, and MRAM Calculator serve as indispensable tools in calculus, facilitating the computation of definite integrals using Riemann Sums. These methods help approximate the area under a curve by dividing it into smaller sections, enabling accurate estimation.

Formula of LRAM RRAM MRAM Calculator

The calculations are based on the following formulas:

LRAM (Left Riemann Sum): LRAM = ∑[i=1 to n] f(a + (i-1) * Δx) * Δx

RRAM (Right Riemann Sum): RRAM = ∑[i=1 to n] f(a + i * Δx) * Δx

MRAM (Middle Riemann Sum): MRAM = ∑[i=1 to n] f(a + (i-1/2) * Δx) * Δx

Where:

  • LRAM represents the Left Riemann Sum
  • RRAM represents the Right Riemann Sum
  • MRAM represents the Middle Riemann Sum
  • f(x) signifies the function being integrated
  • a is the lower limit of integration
  • b is the upper limit of integration
  • Δx denotes the width of each subinterval (Δx = (b - a) / n, where n is the number of subintervals)
