equation for r?

[hollow fossil]

If I say r(h) is greater or equal then 0, how could I make an equation where r depends on h?, is it even possible?

[cold trail]

Is that a C or 0?

@hollow fossil

[hollow fossil]

C, it’s a constant

[cold trail]

Ok

Are we saying h isn’t 0

Or is it a varible

Variable*

[hollow fossil]

H is a variable

[cold trail]

Hmm

[hollow fossil]

I want to make r depend on h

[cold trail]

This complicates things

[hollow fossil]

But I just can’t

[cold trail]

I might be able to calculate when h isn’t 0

[hollow fossil]

Mhmmmm

That’s fine for me

[cold trail]

But idk for sure

But I do know that you could search up the cube function and use that

[wide thunder]

you can do this with a bit of algebra, what have you tried so far?

[hollow fossil]

Just factored out r squared

And then I’m lost

Because I have r+h inside

[wide thunder]

factoring will make it more confusing

[hollow fossil]

[wide thunder]

rewrite it like this then try to solve for h

[hollow fossil]

C/r^2 -r?

[wide thunder]

ye

[hollow fossil]

But that’s just h

[wide thunder]

oh i misunderstood my bad

[hollow fossil]

I want r alone or am just stuck with using the cubic formula

[young tusk]

,w Power[r,3]+Power[r,2]h=C

[young tusk]

this is what happends if you take away r from his friend h

but cubic equation can become that complicated

[hollow fossil]

Welp, I guess there’s nothing else I can do lol, thx however

[cold trail]

And I tried to figure that out on my own 💀

[hollow fossil]

.solved

Solved

Use .unsolved if this was a mistake.

I thought abt it for a sec, because I searched how to find the inverse of a quadratic function, and it used the general formula

Then I googled the cubic formula

And said no no
