To be honest I don’t know. One year they assessed exactly the same things on both papers. Which was crazy. There hasn’t been crashing yet. The Leslie matrix question was very easy. There wasn’t much challenge in the Finance questions. So I imagine you would be more likely to see these things in Paper 2. I also think they need to make Paper 2 a little harder.

@MaffsGuru
@MaffsGuru 3 күн бұрын
The two points you choose must be on the line as you are looking to get the equation of the line from those two points. My suggestion is always choose two point which are on the line AND which cross through two points which are really easy to read from the graph. They don't have to be dots on the line. I hope this helps :)

Hi, thank you for the solutions. But I think you might have made one mistake. For question 33, as it is an undirected graph, edges go both ways. So in that case, there should be a cycle, or multiple cycles in that graph.
@MaffsGuru
@MaffsGuru Жыл бұрын
I don’t really agree and all the teachers and students I have checked with agree with my answer to question 33. a cycle is basically a loop but which passes through more than one point. There is not a way to pass through the points and return to one without repeating.

Thanks for this great work! With qu 22 , just for the process (as the answer is correct- to add $2.47 to $2611.65) don't you need to add the interest on? If the amount was larger it might have made a difference to your answer. But because it was a tiny amount, the 3.9% interest only added altered it from 2.465 to 2.473 so they both round to 2.47. As it was, both the pre and post interest answers were the same when rounded. But the process should include adding the interest to the final payment as just adding it won't usually work. So you set n=1 and include FV as 0, I as 3.9 and find the Pmt?
@MaffsGuru

For question 40, I used the minimum cuts for maximum flows method...and adjusted accordingly with each change. I still got E, but for the change to A, I got an increase of 6 as the maximum flow would become 29 (the new minimum cut). (cutting through DE, DC, AC, GF, GH-total of 29). Is this right? You got an increase of 1. Thanks!

Hi. That's a really good question. One day, I will have a look at what you are asking and see if I can work it out. I don't really understand what you mean by "minimum cuts for maximum flow method" ... sorry. But if you got the same answer, then your method obviously works :)

For question 30, how can the inverse of a matrix be the same as its inverse? I only put 2 correct for that because I could not figure out how the inverse and transpose of a matrix could be the same
@MaffsGuru
@MaffsGuru Жыл бұрын
It's a really small part of the Cambridge textbook. The inverse of an identity matrix is the inverse. It's one of those small things they assess on. I wasn't sure, hence I did the check using the CAS.

Do a Google search for Ti and Hungarian Algorithm and you should see it come up. It’s a great little addition to the CAS.

I went to screen 1.2 and hit MENU -> Matrix -> User defined matrix. This asked for the letter of the matrix I wanted to perform the hungarian algorithm for. I put c. The CAS showed my matrix. I then his ENTER to get the CAS to do the algorithm. I hope this answers your question.

Some of the questions were a little more challenging. The examiners found new and different ways to ask questions about regular content. For example the correcting for seasonality question and the perpetuity question where you needed to have some idea of algebra. I think many of the other questions were fair. Doesn’t make it any better. Fingers crossed you have a really successful day on Monday.

Exactly the same way you did for Paper 1. The chances are there will be repeated content. But as there wasn't crashing, I imagine that will be on there. The Leslie Matrix question on Paper 1 wasn't too challenging and there was no matrix algebra. So perhaps make sure you know how to do this. And consolidate anything you feel you didn't get right on Paper 1. Wishing you the very best of luck though.
