Complex

Select this to allow complex results
in variables.

Use √

If checked, second order polyno-
mials are factorized in complex
mode or in real mode if the dis-
criminant is positive.

Use i

If checked, the calculator is in
complex mode and complex solu-
tions will be displayed when they
exist. If not checked, the calculator
is in real mode and only real solu-
tions will be displayed. For exam-
ple, factors(x

4

–1) yields

(x–1),(x+1),(x+i),(x–i) in complex
mode and
(x–1),(x+1),(x

2

+1) in real mode.

Principal

If checked, the principal solutions
to trigonometric functions will be
displayed. If not checked, the gen-
eral solutions to trigonometric func-
tions will be displayed.

Increasing

If checked, polynomials will be
displayed with increasing powers
(for example, –4+x+3x

2

+x

3

). If not

checked, polynomials will be dis-
played with decreasing powers
(for example, x

3

+3x

2

+x–4).
