Motion Graphs
Enter the equation for velocity: note that if your equation is in the form v = 1/2 t^2  3 you will need to replace "t" with "x" 1. Check the right end of the input box  is there an updown arrow? If YES  Click on the up arrow and select : velocity(x)=If[x>0,1/2x^23] Notice that the condition If[x>0, ] is so the graph begins at time x=0 If NO  type the above into the input box : velocity(x)=If[x>0,1/2x^23] 2. Edit the input by replacing the equation part : for example : velocity v = t^2 modify input to velocity(x)=If[x>0,x^2] 3. Click enter  graphs and equations for velocity, displacement (integral) and acceleration (derivative) will be displayed 4. Note equations can be turned on/off the display by clicking on the dot at the left of each equation 5. When entering trig. functions use parentheses e.g. sin(2x)
