Hello everybody, What is this equation called? I'm from non-English speaking country and I need to look up materials about how to solve it, Thank you.
What is the name of this equation?
- Thread starter Goethe10
- Start date
In summary, the conversation is about an equation with the possible answers being derivatives of it. The equation is not special and can be differentiated to get the answer. The differentials "dy" and "dx" are used in the equation and can be rewritten.

Welcome to PF!
Hello Goethe10! Welcome to PF!
(why have you written a "d" there?)
This is an ordinary equation,
and the four possible answers are dervatives of it,
except that instead of writing dy/dx = f(x), they've written them dy = f(x)dx

Haha, sorry.
It was just smudge done by paint tool, not an actual D, sorry about confusion :P
What do you mean "ordinary equation" Can you please give me the full name? Thanks.

i mean it's just an equation, there's nothing special about, there's nothing to look up!
(just differentiate it!)

Ah, I see! :D Thank you
So
3+2x^3 would be
6x^2
Can you please tell me what does "dy" means?

Goethe10 said:
correct!
if you'd written the equations in full, you would have written:
y = 3+2x3
So dy/dx = 6x2
So dy/dx = 6x2
The "dy" and "dx" in "dy = 6x2dx" are called differentials (or infinitesimal differentials).
You can always rewrite any dy/dx equation so that the dy and dx are on opposite sides …
look that up in almost any book on calculus
