Homework Statement
Find te gradient of the following function f(r) = rcos(##\theta##) in spherical coordinates.
Homework Equations
\begin{equation}
\nabla f = \frac{\partial f}{\partial r} \hat{r} + (\frac{1}{r}) \frac{\partial f}{\partial \theta} \hat{\theta} + \frac{1}{rsin\theta} \frac{\partial f}{\partial \phi} \hat{\phi}
\end{equation}
The Attempt at a Solution
I know that z = rcos##\theta## But I don't know where to go from there since I don't see any ##\hat{r}##, ##\hat{\theta}##, ##\hat{\phi}##
