Differential Equation Graph Window Operations
(4)Drag the stylus across “y’ = exp(x) + x2” 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) + x2 and registers the equation in the differential equation editor ([DiffEq] tab).
(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) + x2 in accordance with the initial condition defined by the matrix and registers the initial condition in the initial condition editor ([IC] tab).
