well fuck a stick up my ass and call me a taffy apple

I've been had

Ok so this is annoying me to no end. No matter how much I google around, I can't find a good explanation for how to *calculate* local and global error in a finite difference scheme, and how they're different.

I understand the basic concept (I think) of local truncation error being the error in the numerical solution from a single step, whereas the global error is the error accumulated from all previous steps up to the current step.

But how the fuck do you actually calculate either one for a specific Finite Difference Method? I can't even find this shit well-explained in textbooks, on google nor on youtube. They all just explain the idea of it, but not how to actually compute it.

Can someone please just explain to me in simple terms how you actually calculate this shit? Like the step-by-step procedures?

Yes I'm a brainlet

>muh racism
Who gives a shit what it's called? We're dealing with a pandemic that's gonna cost potentially millions of lives world-wide and will leave a massive recession in its wake, and you're worried about what people call it? I'm not even right-wing but the fact that THIS is what's concerning people just goes to show how absolutely fucked we are

i really hope the report is wrong.
real bummed out by it.
