Test

The test will take place at 3 pm on Friday 2 November in Week 6.

I would’ve intended that everything up to and including section 2.3 would be examinable for the test. However it looks like we will not finish section 2.3 next week so Section 2.3: Continuity will not be on the test.

You can find the tests I set for the last two years after Exercise Sheet 1 — which is itself after page 49. Also there is a sample from last year here.

As we will not have covered continuity, we will not be able to do the questions two as they are phrased. However we have covered limits.

I will make some brief remarks on these tests now.

“MS2001: Test 1 A Solutions”

  1. Note that we have only done Q. 1(a) using the Alternate Solution given. This question is worth 5/12.5 = 40%; the thinking being that to be of passing standard you must be able to do this ‘exercise’ question.
  2. In light of us not covering Continuity on time, the first part of question could read “Find \displaystyle\lim_{x\rightarrow 0}f(x) or else explain why it does not exist.” To answer this you would have to look at the left- and right-hand limits and invoke Proposition 2.1.3. The second part might ask you “for what values of a\in\mathbb{R} does \displaystyle\lim_{x\rightarrow 1} f(x) exist”, and you would once more have to invoke Proposition 2.1.3. This question is worth 4/12.5 = 32%; the thinking being to get a first you should be able to do the ‘exercise’ question, and this, an ‘exam’ question.
  3. For Q. 3 of the test, you need to know and understand the following definitions: even, odd, increasing, decreasing, quadratic, roots, polynomial, rational function, absolute value, limit, one-sided limit. Q.3 is a harder question and the thinking behind this is that you can get 72% a bare first if you get all of Q.1 and Q.2 — but you will have to be even better than this to get a higher mark. You get one mark for one right, two marks for two right and three plus a bonus half-mark for all three right.

“MS2001: Test 1 A and 1 B Q 3”

I will not ask you for a definition in question two. Again the question could be “Find \displaystyle\lim_{x\rightarrow 0}g(x) or else explain why it does not exist” and “for what value(s) of k does \displaystyle \lim_{x\rightarrow -1}g(x) exist?”

Lectures

We have done up to and including section 2.1.
