PlotsOff CATALOG PlotsOff [1] [, 2] [, 3] ... [, 9] PlotsOff 1,2,5 ¸ Done Turns off the specified plots for graphing. When PlotsOff ¸ Done in 2-graph mode, only affects the active graph. If no parameters, then turns off all plots. PlotsOn CATALOG PlotsOn [1] [, 2] [, 3] ... [, 9] PlotsOn 2,4,5 ¸ Done Turns on the specified plots for graphing. When in PlotsOn ¸ Done 2-graph mode, only affects the active graph. If you do not include any arguments, turns on all plots. 4Polar MATH/Matrix/Vector ops menu vector 4Polar Displays vector in polar form [r q]. The vector must be of dimension 2 and can be a row or a column. [1,3.] 4Polar ¸ [x,y] 4Polar ¸ Note: 4Polar is a display-format instruction, not a conversion function. You can use it only at the end of an entry line, and it does not update ans. Note: See also 4Rect. complexValue 4Polar In Radian angle mode: Displays complexVector in polar form. • Degree angle mode returns (rq). • Radian angle mode returns reiq. 3+4i 4Polar ¸ (4p/3)4Polar ¸ eiø(p2 ì tanê(3/4))ø5 i øp e 3 ø4 complexValue can have any complex form. However, an reiq entry causes an error in Degree In Gradian angle mode: angle mode. 4i 4Polar ¸ (4100) Note: You must use the parentheses for an (rq) polar entry. In Degree angle mode: 3+4i 4Polar ¸ (590ìtanê(3/4)) polyEval( ) MATH/List menu polyEval(list1, expression1) ⇒ expression polyEval(list1, list2) ⇒ expression Interprets the first argument as the coefficient of a descending-degree polynomial, and returns the polynomial evaluated for the value of the second argument. polyEval({a,b,c},x) ¸ aø xñ +bø x+c polyEval({1,2,3,4},2) ¸ 26 polyEval({1,2,3,4},{2,ë 7}) ¸ {26 ë 262} Appendix A: Functions and Instructions 853
