Is there anyone who can help me with the following derivative? I have the following equation, Which I must derive with respect to h:
$$u^{*}=\frac{\alpha +\tau h+\omega \dot{y}+\psi e^{r}(h)}{\left [ s_{w}+(s_{\pi }-s_{w})h\frac{1}{v}\right ]-\beta +\phi}$$
Obtaining the following result:
$$\frac{\partial u^{*}}{\partial h}=\frac{ \tau - s_{w}+(s_{\pi }-s_{w})h\frac{u}{v}+\psi \frac{\partial e^{r}}{\partial h}}{\left [ s_{w}+(s_{\pi }-s_{w})h\frac{1}{v}\right ]-\beta +\phi}$$
Thanks to anyone who will help me.
