How to use left hand riemann sums from a table

The video tutorial explains the concept of uniformity and Delta X, focusing on calculating the left hand approximation using six intervals. It guides through setting up the intervals, determining the left endpoint's height, and summing the heights to approximate the area. The importance of showing the method is emphasized, and an example is provided to illustrate the process.

What is the significance of having a constant delta X in the context of uniformity?

• It ensures equal spacing between intervals.

• It is only important for right-hand approximations.

• It allows for variable interval sizes.

• It makes calculations more complex.

How many intervals are used in the left-hand approximation discussed?

• Four

• Five

• Six

• Seven

In the left-hand approximation, which endpoint's height is used for calculations?

• Middle point

• Right endpoint

• Left endpoint

• Average of both endpoints

What is the sum of the heights used in the left-hand approximation example?

• 26

• 24

• 28

• 20

Why is it important to show the method used in calculations?

• It makes the process more difficult.

• It is not necessary.

• It helps in verifying the results.

• It is only required for exams.
