ᕧ Select EXPLR from the GRAPH menu.
ᕨ Move the free-moving cursor to the initial
condition for which you want to solve.

" # ! $
ᕩ Draw the solution to Q1 , using the cursor
coordinates (x,y) as initial condition
(
t , Q'1(t) ).

To continue drawing more solutions, move the free-moving cursor and then press b.
To stop using EXPLR , press ..
If SlpFld or DirFld is set, the axes are set to specific solutions automatically.
♦
For SlpFld , x=t and y=Q1 are set.
♦ For DirFld , x=Q1 and y=Q2 are set.
If the axes are set to a specific solution t , Q n , or Q' n , that solution is drawn.
If the axes are not set to a specific solution and t is one variable and Q is the other, Q1 is drawn.
If both axes are set to a Q variable, executing EXPLR results in an error.
