The thing is I don't know where to begin with this assignment question I am not looking for a direct answer I just want to know the technique of how I should go about it.


The current I in a circuit is given by:

I = (6x10^-3)(1-e^-1000t)

Use the Chain Rule, find the voltage, V, where V = (6x10^-3)dI/dt

 

This seems to be a fairly good explanation and practical use
of chain rule -

Do you know how to take the derivative of an exponential such as

f(x) = Ae^(ax)

to find df(x)/dx?

Hi,

I think what they are asking here is to break the problem down into two pices:

A^(-a*x)

gets broken down into:
A^x
and:
-a*x

and do each part individually, then combine results in the appropriate way.
That would be using the chain rule.

 

Hi sorry for the late reply. Thanks to all.

Peace, Sean
