Gradient Practice

  • Find the gradient of each of the following functions:

    1. \begin{equation} f(x,y,z)=e^{(x+y)}+x^2 y^3 \ln \frac{x}{z} \end{equation}
    2. \begin{equation} \sigma(\theta,\phi)=\cos\theta \sin^2\phi \end{equation}
    3. \begin{equation} \rho(s,\phi,z)=(s+3z)^2\cos\phi \end{equation}
