(5) Drag the selected expression to the Differential Equation Graph window.
• This registers
y

) on the differential equation editor ([DiffEq] tab). The
Differential Equation Graph window contents do not change at this time.
(6) Drag the stylus across “[[0,1,0][0,2,0]]” on the eActivity application window to select it.
(7) Drag the selected matrix to the Differential Equation Graph window.
• This graphs the solution curves of

y
’ = exp(
x
) in accordance with the initial
condition defined by the matrix, and registers the initial condition in the initial
condition editor ([IC] tab).
Tip
•
An Nth-order differential equation of the form
f
(
y’
,
y’’
…,
x
) dropped into the Differential
Equation Graph Window will be treated as
f
(
