Convergence of f_{n} (x) = π*x*exp(-πx) on (0,∞)

Sequence converge uniformly?

Homework Statement

Define f_{n}: (0,∞) → R, through f_{n} (x) = π*x*exp(-πx), x > 0.
Does the sequence converge uniformly in (0,∞) when n → ∞?

f_{n} = f subscript n

Can somebody please show me all the steps? Any ideas where i can start?

Is the Uniform convergence theorem a good approach?
