Explain to me why Zeta(1/2 + 14 point whatever i) is equal to zero? How does that make any sense? What?

It probably has something to do with where the derivative the eta function changes sign, or something like that. Or maybe just where eta changes sign, I forget.

You don't even need the complex machinery, just a simple sum will give you a crude idea why. could even press it on a calculator, although gl summing 50 terms.

green lines are were zetazeros are. Its not accurate because summing sines and cosines in this regime technically does not converge. Re(z)>1 for it to converge but you can see the trend, it oscillates abit then cuts zero.

How did $x+40/100(8-x) = 90/100.8$ transformed into this equivalent equation $x+40/100.8 -40/100x = 90/100.8$ wich amounts to $60/100x = 50/100.8$ and well I know the result, it's $x = 400/60 = 20/3$ , but what I wanna know is how that transformation occurred.

And it's 100 times 8 and not a decimal 100.8, just to make sure. You never know.
