VCE Methods Question Thread!

PSA:
To those who have a sound knowledge of the VCAA marking system, is using a 0.5mm pacer recommended in the exam (in other words, will the pacer lead smudge off in the exam if VCAA were to scan it?)

[Skitty]

There's a few - I suggest you have a look at past VCAA exam 1s to get an idea of what's required
From the top of my head though - chain/product/quotient rules for differentiation; binomial probability; as well as some version of the general formula for trig functions. I'm sure there's more though.
Please see here for my comment/response regarding this question..
Yueni has also provided an alternative solution

Hope this helps! Post if you require any further clarification

Thanks mate

Pacers and pencils are fine, but I recommend putting your formula sheet behind the page you're working on so you don't smudge the other page while pressing on the current page.

For loge(4x+3)=loge(2x)
Can you just do 4x+3=2x

Yes, because both sides are exactly equal.

However, that will mean x=-3/2, which is outside the domain of x>0 (ie. 2x>0), hence x is undefined.

Just like to wish everyone good luck for the exam, i know you all will kill it!

Hey guys, i know this is a bit last minute but does anyone know if kinematics will play a role in the exam? I have done qutie a few practice exams, and never saw it come up?

There's no rule to stop it from coming or ensure that it does & remember that kinematics is just an application

All the best, everyone. Sending positive vibes!

Last question answer should be C(11/27,16/27).

I got it wrong though. Subbed in x=11/27 into f(x) instead of one of the equations of the line. There goes the 40.

OMG I GOT THE SAME ANSWER HOOORAY!
All my friends were discussing the question and i got a different answer so i was super worried!

Lesson Learnt : Never get worried if a group of people got a different answer to you! You could be the one who got the correct answer !

If you've not prepared much, maybe do couple exams. If you've prepared, I suggest you chill and do something you enjoy eg. gaming. If you really itching to do something, then read some assessor's reports and look over your common mistaes.

They have equated an equation for the tangent to the equation of the curve. This gives a quadratic. How many times does the tangent intersect the graph? Once i.e. the quadratic has one solution. So, the discriminant must be equal to zero.

Hope this helps
