A little question: writing [for example...] 'h(2^nx)' do You mean or ?...
Kind regards
consider summation[(1/2^n)h(3^nx)]
Consider summation[(1/3^n)h(2^nx)]
where h(x)=|x|
I'm trying to see whether these functions are continuous and differentiable.
I know summation[(1/2^n)h(2^nx)] is continuous and not differentiable, but am unsure about theseothers.
