*These starred week numbers are one behind CIT’s week numbers. This is because of the snow.

## Linear Algebra: 20% Test

Results should be released next week along with a copy of the marking scheme and perhaps some further comments.

## Week 7* [21 March]

We had the Linear Algebra Test.

We continued working on statistics by looking at frequency distributions.

## Week 8* Snow Day Catch Up [28 March]

In this class we should be able to finish off the chapter on statistics. This segment of the class will be recorded and published on YouTube.

We will also do Maple Lab 4

## Maple Catch Up

If you have missed a lab you have two options: either download Maple onto your own machine (instructions may be found here) or come into CIT at another time to use Maple.

Go through the missed lab on your own, doing all the exercises in Maple. Save the worksheet and email it to me.

## Independent Learning

Questions you can do include:

• After Week 7*:  P. 89, Q. 1 (a), (b); Q. 2 (b); Q. 3 (b)
• After Week 6*: P. 74, Q. 1-4; P. 77, Q. 1-3
• After Week 5*: P.44, Q. 1-3, Q. 4-5 more abstract. P.47, Q. 1-3, Q. 4 more abstract.  P.56, Q. 1-3, Q. 4 more abstract. P.69, Q. 9 is an important question. A $2\times 2$ version might be

Use only determinants to determine if the following homogeneous system of linear equations has non-zero solutions:

$2x+y=0$

$-6x-3y=0$

• After Week 4: P. 41, Q. 1-4
• After Week 3: P. 28, Q. 1-5, 6-9 have answers with Q. 7 a harder question. P. 34 exercises.
• After Week 2: P. 18 Q. 2
• After Week 1: P. 18 Q. 1, 3 – 6. Harder questions are 7 and 8. For those who do not yet have the manual, see here.

I am not suggesting you should do all of these. It is recommended by the module descriptor that you do two hours of independent and directed learning every week but of course this isn’t feasible for everyone.
