Differential Equation Graph Window Operations
(6) Drag the stylus across “[0,1]” 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
) +
x
2
in
accordance with the initial condition defined by the
matrix and registers the initial condition in the initial
condition editor ([IC] tab).
(4) Drag the stylus across “
y
’
= exp(
x
) +
x
2
” on the eActivity application window to select it.
(5) Drag the selected expression to the Differential Equation Graph window.
• This draws the slope field of
y
’
= exp(
x
) +
x
2
and registers the equation in the
differential equation editor ([DiffEq] tab).
