Any Cove increase calculator out there?

I was hoping to figure out how much it would cost to increase my cove from 635 to 700.

2,184,000 EC

The general formula is:
f(x) = 100*x^2 - 99900*x + 24950000

where x is the number of spaces you want.

f(700) - f(635) = 2184000

So a bit over 2 mill. That's something to gradually work on. Thank you for doing the math.

Even trying to make sense of that equation is making my head go @_@

@pet_cemetery Lol yeah the equation got a little messy! Thank you for posting this! I enjoyed the problem 😊

To make it simpler (and easier to type into a calculator):

100 * [ (# of spaces wanted)^2 - (# of spaces you have)^2 - 999*(# of spaces wanted) + 999*(# of spaces you have) ]

Lol maybe that looks worse, if x is the number of spaces you want, and y is the number of spaces you have its:

100*(x^2 - y^2 - 999*x + 999*y)

@matcha

I'm probably an idiot but what is ^ and *?

matcha • 4 November 2023 at 6:04 PM

@pet_cemetery No worries, symbols mean different thing in different circles so I totally get it!

* = multiplication
^ = exponent

Maybe I should have done it like this

100(x² - y² - 999x + 999y)

where
x = number of spaces you want
y = number of spaces you have

Your example would look like this:

100(700² - 635² - 999*700 + 999*635)

@ matcha
I found the little ^ symbol on the calculator

Hmmm... I fear I did it wrong I got
63,506,500.000


The equation I typed in was
100(700^−635^−999×700+635×999)

matcha • 4 November 2023 at 6:22 PM

@pet_cemetery your calculator probably has a symbol that looks like: x²
If you replace all of the "^" with that you should get the right answer 😊

If you do need to use the ^ symbol, you should also type a 2 right after it 😊

Like: 100(700^2−635^2−999×700+635×999)

You can also just multiply the number by itself, as that is what ^2 means so,

100(700×700−635×635−999×700+635×999)

@matcha

Ha, that works. Thank you for taking the time to explain math to my stupid self.

I saved the equation in a note pad (with a bunch of notes) so if I ever need to use it.

@pet_cemetery Please don't think of yourself as stupid for not knowing a math concept or anything like that.

I actually really struggled in math when going through school and only was able to get better at it when I started studying it as an adult, it wasn't about being stupid then or smart now, but probably just needed to see it in a different environment.

Sorry for the minilogue, I'm always happy to help in any math related adventures 😊
