What is the Trapezoidal Rule used for?
Think of dividing shapes into simpler parts.
What is a planimeter?
Consider a tool that 'walks' around a shape.
What does the Trapezoidal Rule approximate?
Think about shapes that have parallel sides.
Simpson's Rule uses what to estimate area?
Visualize how curves fit within lines.
A plot measures 12 meters on one side, 14 meters on another, and the remaining two sides create a trapezoidal section with heights of 5 meters each. Calculate the area using the trapezoidal rule.
Remember to average the lengths of the bases.
Using coordinates, calculate the area of a polygon with vertices at (2,3), (5,11), (12,8), and (10,5).
Use the coordinate formula carefully.
