z(x,y) = e^{x^2y}, \quad x(r,\theta) = rcos\theta, \quad y(r,\theta) = rsin\theta 1) Write the chain rule formula for $\frac{\partial z}{\partial r}$. Ans: $\frac{\partial z}{\partial r} = \frac{\partial z}{\partial x}\frac{\partial x}{\partial r} + \frac{\partial z}{\partial y}\frac{\partial y}{\partial r}$ ii) Show that $\frac{\partial z}{\partial r}$ can be written as follows $\frac{\partial z}{\partial r} = (3r^2 cos^2 \theta sin\theta)e^{r^2 cos^2 \theta sin\theta}$ CONFIDENTIAL iii) Evaluate $\left. \frac{\partial z}{\partial r} \right|_{r=1, \theta = \frac{\pi}{4}}$. Ans: $\left. \frac{\partial z}{\partial r} \right|_{r=1, \theta = \frac{\pi}{4}} = \left( 3(1)^2 cos^2 \left(\frac{\pi}{4}\right) sin\left(\frac{\pi}{4}\right) \right) e^{(1)^2 cos^2(\frac{\pi}{4})sin(\frac{\pi}{4})} = 1.5105$
