*Easter might provide extra time to put into Chapter 3.*

## Matrices Test — Corrections

I have a bit of a backlog of corrections but hopefully I can get these to ye before Easter Sunday.

## Week 9

### Lectures

Final two sections of Chapter 3:

- Partial Differentiation I (31 minutes)
- Partial Differentiation II (38 minutes)
- Error Analysis using Differentials (30 minutes)
- Error Analysis Example (5 minutes)

Here are last year’s lectures of the same material:

- Functions of Several Variables (12 minutes)
- Partial Differentiation: Theory (25 minutes)
- Partial Differentiation: Examples (11 minutes)
- Higher Order Partial Derivatives (21 minutes)
- Partial Differentiation Tutorial (9 minutes)
- Differentials (10 minutes)
- Propagation of Errors (7 minutes)
- Propagation of Error Examples (25 minutes)

### Exercises

How much time you put into homework is up to you: of course the more time you put in the better but we all have competing interests. Please feel free to ask me questions about the exercises.

Try:

- p. 143, Q. 1-5 [Note these exercises are
*interleaved –*there are questions here from earlier sections in Chapter 3] - p. 150, Q. 1-6 [Note these exercises are
*interleaved –*there are questions here from earlier sections in Chapter 3]

Additional Exercises: p. 143, Q. 6, p. 151, Q.7-8, 9-10

Submit work for Canvas feedback by Sunday 28 March for video feedback after Monday 29 March.

## Outlook

I will be providing learning support over Easter.

Looking further ahead, to after Easter, a good revision of integration/antidifferentiation may be found here. Here is some video of revision of antidifferentiation.

## Week 10

Perhaps of the order of 1.5 hours of lectures on starting Chapter 4 on (Further) Integration with a revision of antidifferentiation, and a look at Integration by Parts. We will use implicit differentiation to differentiate inverse sine.

## Week 11

Perhaps of the order of 1.5 hours of lectures on completing the square, and work.

## Week 12

Perhaps of the order of 1.5 hours of lectures on centroids of laminas and centres of gravity of solids of revolution.

## Assessment Schedule

**Week 11 ** – 25% Differentiation Test *(Zoom Tutorial in Week 10, after Easter)*

**Week 14 **– 25% Integration Test *(Zoom Tutorial in Week 13)*

## Study

Please feel free to ask me questions about the exercises via email. I answer emails every morning seven days a week.
