Get started for freeThe parametric equations for the paths of two projectiles are given. At what rate is the distance between the two objects changing at the given value of \(t ?\) \(x_{1}=48 \sqrt{2} t, y_{1}=48 \sqrt{2} t-16 t^{2}\) \(x_{2}=48 \sqrt{3} t, y_{2}=48 t-16 t^{2}\) \(t=1\)
Use the function $$f(x, y)=3-\frac{x}{3}-\frac{y}{2}$$ Find \(\nabla f(x, y)\)
The function \(f\) is homogeneous of degree \(n\) if \(f(t x, t y)=t^{n} f(x, y) .\) Determine the degree of the homogeneous function, and show that \(x f_{x}(x, y)+y f_{y}(x, y)=n f(x, y)\) \(f(x, y)=\frac{x^{2}}{\sqrt{x^{2}+y^{2}}}\)
Differentiate implicitly to find the first partial derivatives of \(w\). \(x^{2}+y^{2}+z^{2}-5 y w+10 w^{2}=2\)
Find \(\partial w / \partial s\) and \(\partial w / \partial t\) using the appropriate Chain Rule, and evaluate each partial derivative at the given values of \(s\) and \(t\) $$ \begin{array}{l} \text { Function } \\ \hline w=x^{2}-y^{2} \\ x=s \cos t, \quad y=s \sin t \end{array} $$ $$ \frac{\text { Point }}{s=3, \quad t=\frac{\pi}{4}} $$
