Step 1
Step 1:** Calculate the values of \(r\) and \(s\) at the given point \(P\): \(r = y + x \cos(t) = 5 + 1 \cdot \cos(0) = 6\) \(s = x + y \sin(t) = 1 + 5 \cdot \sin(0) = 1\) ** Show more…

Use the Chain Rule to find the indicated partial derivatives. $$ \begin{array}{l} z=x^{4}+x^{2} y, \quad x=s+2 t-u, \quad y=s t u^{2} \\ \frac{\partial z}{\partial s}, \frac{\partial z}{\partial t}, \frac{\partial z}{\partial u} \quad \text { when } s=4, t=2, u=1 \end{array} $$
Partial Derivatives
The Chain Rule
Use the Chain Rule to find the indicated partial derivatives. $ T = \dfrac{v}{2u + v} $, $ u = pq\sqrt{r} $, $ v = p\sqrt{q}r $; $ \dfrac{\partial T}{\partial p} $, $ \dfrac{\partial T}{\partial q} $, $ \dfrac{\partial T}{\partial r} $ when $ p = 2 $, $ q = 1 $, $ r = 4 $
