1.4 Calculation of Area Under Curves

Author: Ian VanderSchee

Learners will approximate areas under curves using rectangles and/or trapezoids.

Learners will strategize how to make the approximate areas more accurate, using more rectangles/trapezoids of smaller width.

Learners will analyze whether a given approximation is an overestimate or an underestimate of the actual area.

As a lead-in to the future topic of integration, areas are calculated using rectangles and/or trapezoids.
