Does anyone have this calculator?

http://h20426.www2.hp.com/product/calculators/docs/learning_modules/sc300s/datasheet_sc300s.pdfIf 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.?
