Uniform convergence of a sequence of functions.
Not what you're looking for?
1. Show that the sequence x^2 (e^-nx) converges uniformly on [0, infinity).
2. Show that if a is greater than zero then the sequence (n^2 x^2 (e^-nx)) converges uniformly on the interval [a, infinity) but does not converge uniformly on the interval [0, infinity).
For problem 2 text gives a hint that if n is sufficiently large, ||f_n||_[a,infinity]=n^2 a^2/e^na , however ||f_n||_[0,infinity)=4/e^2 (A _ is used to denote a subscript).
