Suppose $f$ and $f^{-1}$ are differentiable functions. Suppose $f(3) = -9$ and $f'(3) = -7$. Question 1 $(f^{-1})'(-9) = \boxed{-\frac{1}{7}}$ Question 2 Set $h(x) = \frac{f^{-1}(x)}{\arctan(\frac{x}{-9})}$. h'(-9) = \boxed{}$
10-60 Consider a steady, two-dimensional, incompressible, irrotational velocity field specified by its velocity potential function, $\phi = 4(x^2 - y^2) + 6x - 4y$. (a) Calculate velocity components $u$ and $v$. (b) Verify that the velocity field is irrotational in the region in which $\phi$ applies. (c) Generate an expression for the stream function in this region.
