Differentiate y = 1/(s + ke^s): How in the heck do you do this?

Differentiate

. . . . .y = 1/ (s + ke^s)

How in the heck do you do this?

y = 1/ (s + ke^s)

Do you know Chain rule of differentiation?

First either use the quotient rule or write it as \(\displaystyle y= (s+ ke^s)^{-1}\) and use the chain rule. The important thing is to try something! Give it a shot and get back to us. (I assume you want to differentiate with respect to s but you really should say that.)
