Setting Purpose (Cont.)

Complex Use √

Select this to allow complex results in variables.

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(x4–1) yields
	(x–1),(x+1),(x+i),(x–i) in complex
	mode and
	(x–1),(x+1),(x2+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+3x2+x3). If not
	checked, polynomials will be dis-
	played with decreasing powers
	(for example, x3+3x2+x–4).
