Key things to know how to do on a Casio Classpad 330?

[Bazinga!]

Hey guys! What are some key things to know how to do on the classpad 330? Thanks!!

Program your shift keys, so you're not reaching for the finicky soft keyboard each time you want to use logs, trig functions, calculus, etc.

If integrating a trig function with a constant, take it out first always. Calc will sometimes freeze or crash ('!' mark in the flashing 'calculating...' box) depending on how complex the expression is, always try and simplify it as much as possible for the calc. In addition to this, you also should take out any constant since the calc can decide to go rogue and give you a dodgy answer which you will have no way of knowing in the exam.

tl;dr: classpad is a piece of crap and we need to do our best to work around its shortcomings.

That's from my experience, as for techniques I'm guessing by using it for at least 2 years you already have all the essential tricks with you. (know how to find inverse, judge, etc.)

What does judge do? I have the Casio 330 and I've never used it before.

What does judge do? I have the Casio 330 and I've never used it before.

It's for the questions where they say something like:

For the functional equation f(xy) = f(x/2) + f(y/2), a possible function that satisfies this could be:
A)
B)
C)
D)
The choices will be stuff like ln(x), cos(x), etc. and you would sub one of those functions into the above functional equation then you use the judge function where the calculator will say TRUE or FALSE, where true means that function satisfies the above equation and thus would be the correct answer.
To speed up the process, define the functional equation first.

A bit of a watered-down explanation but I hope you get how it would assist in solving such questions like above.

EDIT: Pretty sure there's also some guide on how to do these questions somewhere.

I've never even seen the judge operation on my calculator before. I've been wasting so much time on these questions for no reason. >_<

I wonder what else I've missed...

Oh wow! I just did a question with the judge function and it took me like 30 seconds rather than a couple of minutes.
