which simplifies to
and s ince you are told that f(0) = 2, this means
Now take the derivative of f(t) using the chain rule for each term:
This simplifies to:
and since you are told that f ' (0) = 1,
Thus you have two equations involving two unknowns and you can solve this in any of the usual ways. Cheers,
