Lets assume that you are asking about the derivative of:Originally Posted bydemi

.Well this can be done in a number of ways, you could use the quotient rule,

or the product rule to find this derivative. Now I don't have that good a

memory, and so never bother with the quotient rule, always using the product rule:

.

Here we let:

,

and:

.

Now:

,

and:

.

So now you have enough to assemble the derivative
