# Thread: how to differentiate this?

1. ## how to differentiate this?

Hi, I have to differentiate z=w^3/2(w+ce^w)
does anyone know how to do this?
Thank you in advance

2. ## Re: how to differentiate this?

You could use the product rule, have you tried that?

3. ## Re: how to differentiate this?

Or the Quotient Rule...

\displaystyle \begin{align*} \frac{d}{dx}\left(\frac{u}{v}\right) = \frac{v\,\frac{du}{dx} - u\,\frac{dv}{dx}}{v^2} \end{align*}

I am confused by your use of parentheses.

Do you mean z = (w^3/2)(w + c*e^(w))

OR

do you mean z = (w^3)/(2(w + c*e^(w))?
See the difference?
