**Derivative**

In the class ‘what is a derivative?(Optional)’

Can somebody explain how that the J(w) is increasing by 6 times if w is increasing by 0.001?

I tried:

As per the statement, I think J(W + Epsilon)/J(W) should be equal to 6.

but am not getting the same though.

It isnt. It is increasing by 0.006.

Hey @Devarapalli_Vamsi,

This is just the same idea as Tom said, but if we pay more attention to the subtitle, for example, , it is 6 times Epsilon instead of 6 times J(w). So, if epsilon is 0.001, then 6 times epsilon is 0.006, and J goes up by 0.006.

Cheers,

Raymond
