Riemann approximation introduction (6:44) Approximate the area of the region under the curve
bounded by
and
.
Over and under estimation on Riemann sums (4:00) The graph of
is given. Consider the left and right Riemann sums that would approximate the area under
between
and
. Are the approximations underestimations or overestimations?
Worked example: finding a Riemann sum using a table. (6:38) Given a table of values of a function, find a Riemann sum of that function.
- * Practice: Left and right Riemann sums. (4 problems)
Worked example: over and underestimation of Riemann sums. (4:41) Ordering different areas from least to greatest.

Midpoint sums (5:28) Approximate the area under the curve
bounded by
and
using three rectangles of equal width.
