#### fx-100AU Plus 2nd Edition

CASIO supply the Australian market with two scientific calculators, the fx-82AU and the fx-100AU. What is the difference? In the simplest terms, the 100AU has more functions than the 82AU but uses a more traditional entry mode.

These differences can be explained in more detail under three main points:

1. The 82AU provides the option to use latest in input method (natural display or MATH, for example fractions can be entered as fractions). You can, however, also use LINE input on the 82AU where the use of brackets becomes important. The 100AU only offers LINE input.

2. The 82AU’s functionality is largely a subset of the functionality offered by the 100AU. The 100AU offers more functionality, mainly involving higher order functions. For example binary computation, complex number computation (polar and cartesian) and a host more.

3. The 82AU provides list-based Statistics input, whereas the 100AU does not.

To convert between rectangular and polar coordinates, first you enter the form you want for the output, then enter the two parameters of the input form (x & y or r & theta) . The outputs are stored in memory E and memory F, and can be recalled as required.

For example, to convert (2,5) to polar coordinates

Press e2,5)p

The outputs values are stored as follows ‘r’ is stored in memory E and theta is stored in memory F.

E can be recalled by pressing Qkp and F can be recalled by pressing Qlp.

To convert r=3 and theta=60 degrees to rectangular coordinates

Press qe3,60)p

The outputs values are stored as follows ‘x’ is stored in memory E and ‘y’ is stored in memory F.

E can be recalled by pressing Qkp and F can be recalled by pressing Qlp.
