Question
Find $f_{x}, f_{y},$ and $f_{z}$$$f(x, y, z)=\cosh (\sqrt{z}) \sinh ^{2}\left(x^{2} y z\right)$$
Step 1
To do this, we treat $y$ and $z$ as constants and differentiate the function with respect to $x$. Using the chain rule, we get: $$ f_{x}(x, y, z)=2 x y z \cosh (\sqrt{z}) \cosh \left(x^{2} y z\right) $$ Show more…
