How to use the Solutions Tool

Setting Initial Conditions

• Click the mouse on the tx graphing plane to set the initial conditions for trajectory and define the constant for the solution function.
• When you pass the mouse over the tx plane the functional relationship between the variables is shown.

Equations

• Click the arrow button to the left of the equation to pop up the list of equations.
• Click an equation to select it.

Time Step Buttons

• Click the mouse on a button in the t  list to set the time step for the trajectories.

Other Buttons

• [Draw Field] draws a slope field over the graphing plane.
• [Clear] removes all slopes and trajectories from the graphing plane.
• [Euler] draws a solution by Euler's method.
• [Runge Kutta 4] draws a solution using the Runge Kutta technique.
