Help with Derivatives
Dragomistress:
So what does the d/dx mean?
Or is the same as dy/dx?

So I use the d/dy when there is no designated letter for a value for convenience?
For example solve the derivative of: (3x+4)^3
d/dx (3x+4)^3 = 9x(3x+4)^2
Instead of writing
Let y = (3x+4)^3
dy/dx = (3x+4)^3
= 9x(3x+4)^2

Yep that's perfect!
Dragomistress:
Now I just feel like I am abusing the forum for questions :/ but I just truly don't understand.
How do I do this using the quick formula?
