Homework Statement
show a function f_n is not uniformly convergent using a theorem:
Homework Equations
if f_n converges uniformly to F on D and if each f_n is cont. on D, then F is cont. on D
The Attempt at a Solution
not really sure what to do. use the contrapositive? would that be, then, if F is not continuous on D, then either f_n is not uniformly convergent on D or each f_n is not cont. on D? specifically, the function is f_n=e-nx. i think if i understand how to apply the theorem, it shouldn't be too hard.
