Hi all,
i have a specific problem of finding the point at which the dependent 
variable takes on a particular value in teh solution of a differential 
equation.
e.g. for simplicity
we have the equation y'[t]==t, and the initial cond. y[0]==0.y is the 
dep. variable and t is the independent variable.
i want to find out the 't' at which y[t]==p(p is known, say 8)
and since i am already using NDSolve to solve this and other equations 
i'd like to achieve this working around NDSolve,
could anyone suggets a solution to this problem??
thanks a ton!
Pradeep
