k Calculation Priority Sequence
This calculator employs true algebraic logic to calculate the parts of a formula in the following
order:
1 Type A functions
• Coordinate transformation Pol (
x , y ), Rec ( r , θ )
• Functions that include parentheses (such as derivatives, integrations, Σ , etc.)

You can combine the contents of multiple function memory (fn) locations or graph memory
( Y n, r n, X tn, Y tn, X n) locations into composite functions. Specifying fn1(fn2), for example,
results in the composite function fn1
°
fn2 (see page 5-14). A composite function can consist
of up to five functions.

Metric conversion commands are supported only when the Metric Conversion add-in application
is installed.
