Would the CASIO give exact trigonometric answers? For example, sin(60) = (root3)/(2) rather than a number to x decimal places?

I honestly don't know. The 2 year old model casio I have puts it into decimals. But the TI-30xb gives out nice fractions.

I bought the TI-30XB multiview. It's AMAZING. It may not have as many of the functions as the Casio, but I think it's simplicity is what makes it so amazing. It has everything you need for the sciences, and it's not so complicated; you don't have to go through so many secondary functions to get what you need.
Personally, as a TI-Nspire user, the variables and STO-> (store) buttons are incredibly useful especially when you are dealing with so many different values. If you use the Nspire, I especially recommend it because it will be very familiar. The other scientifics are just unnecessarily complex in my opinion. ALSO...it's crazy thin unlike the Casio. (the sharp is pretty thin as well)

p.s. I really hate calculators as a maths person...so this is glowing praise from me.

Does anyone have this calculator?
http://h20426.www2.hp.com/product/calculators/docs/learning_modules/sc300s/datasheet_sc300s.pdf

If so would it work well with trigonometric functions eg. sin(60) = (root3)/2 rather than fractions?

This calculator does have a range of functions eg. log to any base etc., except the buttons are small.
Although if you were using a normal scientific calculator you could just use the log10(a)/log(10)(b) (or loge/ln) to achieve the same result (where a and b represent numbers depending on the situation).

In regard to 'polar-rectangular conversions' what would that consist of?
I understand that it incorporates complex numbers, but what exactly do you do to get answers etc.?

I am yet to purchase a TI-30XB multiview. But it's good to hear good feedback about it :)

How much is the TI-30xb? :)

I have one of those brick CASIO scientific calcs haha, fx-82TL
