Riemann Sum Progression: From Rectangles to Definite Integral
A visual progression from a coarse partition to a definite integral, with width, height, and limiting behavior labeled.
Reference format12 min estimated timeFoundational progression
What is included
See how increasingly fine Riemann sums approximate signed accumulation and lead to a definite integral.
Skills assessed
- interpreting Riemann sums
- connecting sums to integrals
Prerequisites
- function graphs
- sigma notation
Long description
Read the diagram from top to bottom. Each numbered box names one decision or mathematical operation. Arrows show the required order; the text labels remain the complete interpretation in print, dark mode, and nonvisual reading.
