I'm trying to understand something. Derrivatives are basically the same as differentials. The both apply to the chnange in XY values.(adsbygoogle = window.adsbygoogle || []).push({});

Now I have an eqaition y=x*x x*x=x sqaured.

So that being here are my XY values

X y

_______

1 1

2 4

3 9

4 16

5 25

So that being dv=2x . But if you plug that in x the change is different.

WIth that eqauition if x=1 the change in y should be 2. So if x changes by 1. But is chnage x by 1 y becomes 4.

If x=2 the change in y should be 4. But if we change x by 1 y=9 not 8.

What's going on?
