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 o n l y 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 b o t h
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 E Q s 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 E Q ” by pressing O K
■ 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 E Q s , and then editing the list
using E D 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 r i g h t - h a n d
s i d e e x p r e s s i o n s 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.
