Question

How do you differentiate `y=1/(x+ke^s)`?

Answer 1

`y=-(x+ke^s)^-2`

Explanation:

Rather than use quotient rule, rewrite the equation so that there's nothing in the denominator by raising everything to `-1`:

`y=(x+ke^s)^-1`

Now use the chain rule. I'm asssuming `k` and `s` are constants:

`y=-(x+ke^s)^-2`
