Suppose I'm solving a differential equation with NDSolve :
NDSolve[{ x'[t] == f[ x[t] ], x[0] == 3.4 ], { x }, {t, 0, 10}]
Mathematica then finds a solution like this :
Out[]= {{ x -> InterpolatingFunction[{{ 0., 2.6532}}, <>}}
Next, I need to make several graphs of the solution. How can I point to the max value t = 2.6532 without retyping that value each time, especially if I change the initial condition x[0] == 3.4 and redo NDSolve again ? What is the name of the t_max found by Mathematica ? Or how can I point to that special value ? Is there a way ?
