For those who had done quite a few VCAA exam 2's, I want to ask did you notice any questions that whole freeze your calculator?
It happened to me once from doing an exam paper from another company and it means that I have to reset my calculator and lose all the stored functions.
Just wondering, would VCAA ensure the equations and questions that require calculator solving won't be too long to solve so that the calculator won't freeze?

Generally, solving for Trig function's take's a long time...

Suggestion: don't reset, just pull the batteries out, everything should be kept and the calculation will stop :)
I think usually those questions are made to be attempted differently, eg. by hand etc.

If it freezes, just press the ON button to stop whatever you are doing.
If you are finding that solving is taking too long, try to use nSolve with a specified domain, or sketch the graphs and solve via intersection of two curves.

If you are using a classpad, in the bottom right hand corner of the screen click the "esc" button if you ever want to stop the calculator from loading
-
Alright thanks for the advice.

WHY DIDN"T I KNOW THIS FOR SPESH?

Omg Any other cool tips?
-
haha sorry that's all ive got. but yeah im speaking from experience too. went terribly wrong in a sac once when i accidentally tried to solve a trig equation with a domain of 1000.... learnt about it after that

Or you can press clear.
But it's pointless, you don't get the answer.

does anyone know how the "dsolve" function differs from normal "Solve" on a casio classpad?

I can't stand the CAS calculators. Sure, they have more controls than the space shuttle and can help process the most difficult of questions as a "get out of jail free" card, but they just feel WAY too cumbersome.
I strongly prefer Exam 1 as I prefer to "pack light" with just a pencil or two, an eraser, a sharpener and my brainpower.
CAS Calc took AGES to process a question on TSFX 09 today...

Yes, CAS is an abomination. It produces so many issues... peoples calcs not working, different calcs working differently. The calc costs money when education is free, yet is a necessity... etc.

Yea the thing is I *think* VCAA would ensure that the calc won't take too long to solve the questions so that hopefully no one freaks out from calculator freeze

Or they might decide to throw in an equation in which the Calculator may or may not want give "More Solutions Exist."
-
like a polynomial with a trig, just graph em.
-
Yeah, when it's possible I just push clear on the classpad to break the operation, then use the graph instead.
-
cheers for link.
-
that is a good link, too bad I don't need to use it anymore :/, had to struggle through the fail solving speeds for the year
-
Do fellow classpad users have issues with finding the median of a continuous PDF? How do you go about doing it... I always get no solutions!
I can't find any problems, can someone post a 'find the median of this contin PDF' bla bla problem up? So I can fiddle with it...

I agree with the hatred of CAS, but count yourselves lucky that you get a non-calc exam. Wasn't it only calc like 5-6 years ago?

Yes, a decade or so ago I recall you were allowed to bring in calcs for both exams, but they couldn't do like algebra and weren't as powerful as they are now - so you would have to do some questions manually and some with the calc.

Completely different story with Spesh ... From memory the last question in 09 took 3 minutes or something. And if you didnt specify the domain properly it gave a different solution to what was required. Worst question ever.
