Unit 4 trapezoidal sum approximation from a table

The video tutorial explains the trapezoidal rule for numerical integration, detailing how to calculate the area under a curve by dividing it into trapezoids. It covers the process of calculating function values at specific intervals, performing arithmetic operations, and simplifying results to find the approximate total area.

Explain how the intervals are handled in the calculation process.

What is the final approximate value calculated in the text?
