1. Use the same general procedure as for plotting an expression,

but make note of the following differences when the plot type is

■ For equations whose left-hand side consists only of the name of

the dependent variable (such as y = — 7.c -f 29), only the

right-hand side expression is plotted.

■ For equations whose left-hand side consists of some expression

other than the name of the dependent variable (such as

sin.c = cos*), the left-hand and right-hand expressions are both

plotted.

1. Press (r^fPLOT) to open the PLOT application.

2. Do one of the following to enter a list of the expressions or

equations into the EQs field.

■ If all of the expressions or equations are stored in variables, press

C H 0 U S, move the arrow keys to highlight each expression or

equation in turn, and press v'CHK to select it. Return a list of

all checked equations to EQ” by pressing OK

■ Type

(5DCIZ)

begin a list and then type each expression or

equation in as an element of the list. Press (ENTER) to enter the

list into Euii .

■ Combine the previous two approaches by selecting those

expressions and equations that are stored in variables into a list

using CHuUS, entering it into EQs, and then editing the list

using ED I T . You may add, insert or modify equations in the

list.

Note that each expression or equation in the group must be

appropriate for the given plot type (see chapter 23 for details).

Also, when equations (containing the sign) are included in a list

to be plotted using the Funct ion plot type, only the right-hand

side expressions of each equation is plotted. The left-hand side

expressions are ignored. You may wish to rearrange some equations

so that they are expressions (or equations whose left-hand side is

zero).

3. Enter values for the plotting parameters and display options, if

necessary.
