ok so i'm kinda sort of confused...
I had this for a equation
X^2 + 4X - 1 = 0
and then I was like zero???
zero... really zero...
X^2 + 4X - 1 = dy
That zero does represent when Y equals zero correct??? this allows us to solve for X
wait so I'm confused...
I'm not solving for X really am I... I actually solving for the derrivative of y??? when y approaches infinitely small or other words zero???
I'm confused can you clear this up for me
Context would help. What is the original problem?
