Let $f:U\subset\mathbb{R} ^3\rightarrow \mathbb{R} ^2$  given by $f(x,y,z)=(sin(x+z)+log(yz^2) ; e^{x+z} +yz)$  where $U = { (x, y, z) ∈ R^3| y, z > 0 }.$  Questions Inside.  $20.00 answered 1. Prove that $f$ is class $C^{∞} $  and calculate the Jacobian Matrix in $(0,1,1)$.2. Considering $R^3 = R^2×R$, calculate the partial derivatives $D_{i}f(0, 1, 1)$ with $(i = 1, 2)$.3. Using the The...
