## plotting array over range larger than ar...

Maple

Hi, I'm running into difficulty regarding plotting an array I have.  I have an array of 500 elements and each element corresponds to an even integer.  Hence I want to plot for x=1..1000 where array[1] is plotted at x=2, array[2] is plotted at x=4 etc, and the odd numbers are left empty.  How do I do this.  I tried

fn := proc(n)
global array:
if n mod 2 = 0 then return array[n/2]:
end if:
end proc:

## Trivial zeroes of Riemann zeta function ...

Maple

Hi, sorry to open a new thread but the last one just got a bit too messy.

mathbin.net/5767 - What I want to do.

mathbin.net/5850 - What I have tried to do so far.

Any help on this would be greatly appreciated.  Thanks

## Plot involving non-trivial zeroes of zet...

Maple

My problem statement is here - mathbin.net/5767

Now,  I want to know if this would be relatively simple to plot?  I hope to find a table of the non-trivial zeroes somewhere to save maple computing them.  If I did that, does anyone know how I would plot this?

For anyone interested, this is supposed to simulate the prime counting function.

Thanks,

tom

## Riemann zeta plot...

Maple

Hi there, could someone help me plot zeta(0.5 + it) as seen here - en.wikipedia.org/wiki/File:Zeta_polar.svg

I assume I need to import some complex plot package?

## prime counting function...

Maple

This may have an annoyingly simple answer but I cannot seem to plot the prime counting function

with(numtheory):
plot(pi(x), x=0..100);

This just gives me an empty plot.  Any ideas?
