Inputting Initial Condition and Graphing the Solution Curve of a Fir t
Order Differential Equation
You can use the procedure in this section to overlay, onto the slope field, solution curves of
the first order differential equation input on the [DiffEq] tab for given initial conditions.
Example: To input the first order differential equation y ' = y
graph three solution curves for the initial conditions ( xi , yi ) = (0,0), (0,0.5), (0,1)
Cla Pad Operation
(1) Use the procedure under "Inputting a First Order Differential Equation and Drawing a
Slope Field" on page 14-2-1 to draw the slope field for y ' = y
(2) Activate the Differential Equation Editor window and then tap the [IC] tab.
• This displays the initial condition editor.
(3) On the initial condition editor, input the following initial conditions: ( xi , yi ) = (0,0), (0,0.5),
(0,1). Perform the following operations.
(4) Tap .
• This graphs the three solution curves over the slope field of y' = y
