First 3/4 methods SAC

[zxcvbnm18]

HaS anyone had their first 3/4 methods sac for this year yet? If so, how was it and what  kind of questions were on the sac?

Hello! I did Methods last year, but I can tell you what came up.

As far as I remember, there was trig, implied domain, inverse functions, speed-distance-time application questions, logs and log graphs, exponentials and their graphs, square root graphs etc etc.

Our school divided the sac into three days, with four hours in total. We had 2 hours after school Wednesday, 1 hour Thursday and 1 hour Friday. I remember the Wednesday part being the hardest (speed-distance-time questions were really tricky!) and Thursday's part being the easiest (basic graphing and calculation. Application questions weren't too hard)

If you do most of the textbook questions (and try to do all the chapter review questions if you can!) and do any practice sacs your school gave you, then you have good preparation for it

And even if you don't end up doing as well as you thought, don't lose hope! The exam, after all, is what counts the most towards your study score. See the sacs as a diagnostic of how you're going so far in the year leading up to the exam.

Hope that helped!

I just got the first part of my application task for methods today and it was a fairly straight forward investigation on functions and differentiation, focusing on the mean value theorem. I'm assuming all schools have to choose a 'theme' for the task and then have several sections of the SAC conducted separately, given the details on the VCAA website.

Thnx but what is the mean value theorem?

Thnx but what is the mean value theorem?

If f(x) is defined and continuous on the interval [a,b] and differentiable on (a,b), then there is at least one number c in the interval (a,b) such that:

No it's not actually part of the course, but in the application task you are supposed to be introduced to a mathematical concept you do not have foreknowledge of, but is still an application of stuff you know about. In this case, the mean value theorem is an application of functions and differentiation.
