Squareroot as a function

[sly peak]

1. Wait patiently for a helper to come along.
2. Once someone helps you, say thank you and close the thread with:

+close

3. Feel free to nominate the person for helper of the week in #helper-nominations
4. Do not ping the mods, unless someone is breaking the rules.
5. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

cause that's the outside function

$u:=6+t^2$ makes $\sqrt{6+t^2}=\sqrt{u}$

Yeah, but where does it come from?

Sqrt in itself isn’t a function

[worldly breach]

it is

it's a function with natural domain $[0,\infty)$

Can 0 be a solution to a homogenous differential equation?

[worldly breach]

sure, any function in theory can be the solution to a DE (assuming it's sufficiently differentiable)

what that question has to do with whether a map is a function or not... no clue lol

[distant mulch]

Oh they weren't related lol hahah
