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).
