Using the DIFF EQ Mode

6. Specify variables to graph or to store in LIST.

Press 5(SET) and select c(Output) to display the list setting screen.

x, y, y

(1)

, y

(2)

, ....., y

(8)

stand for the independent variable, the dependent variable, the

first order derivative, the second order derivative, ....., and the eighth order derivative,

respectively.

1st, 2nd, 3rd, ...., 9th stand for the initial values in order.

To specify a variable to graph, select it using the cursor keys (f, c) and press

1(SEL).

To specify a variable to store in LIST, select it using the cursor keys (f, c) and

press 2(LIST).

7. Press !K(V-Window) to display the V-Window setting screen. Before you solve a

differential equation, you need to make V-Window settings.

Xmin … x-axis minimum value

max … x-axis maximum value

scale … x-axis value spacing

dot … value corresponding to one x-axis dot

Ymin … y-axis minimum value

max … y-axis maximum value

scale … y-axis value spacing

8. Press 6(CALC) to solve the differential equation.

• The calculated result is graphed or stored in the list.

# Only the slope fields are displayed if you do

not input initial values or if you input the wrong

type of initial values.

# An error occurs if you set SF to zero and you

do not input the initial values, or if you input

the initial values inappropriately.

# You are advised to input parentheses and a

multiplication sign between a value and an

expression in order to prevent calculation

errors.

# Do not confuse the - key and the - key.

A syntax error occurs if you use the - key

as the subtraction symbol.

# An error occurs if you input variable

y in the

function

f(x). Variable x is treated as a

variable. Other variables (A through

Ζ, r,

excluding X and Y) are treated as constants

and the value currently assigned to that

variable is applied during the calculation.

# An error occurs if you input variable

x in the

function

g(y). Variable y is treated as a

variable. Other variables (A through

Ζ, r,

excluding X and Y) are treated as constants

and the value currently assigned to that

variable is applied during the calculation.
