Most Upvoted Answer
Let f : R → R be a twice differentiable function. If g(u, v) = f(u2 – ...
Chain Rule Application:
The function g(u, v) can be thought of as a composition of functions, where the outer function is f and the inner function is u^2 - v^2. To find the partial derivatives of g with respect to u and v, we need to apply the chain rule.
Partial Derivative with respect to u:
To find ∂g/∂u, we differentiate g with respect to u treating v as a constant. Using the chain rule, we get:
∂g/∂u = ∂f/∂x * ∂(u^2 - v^2)/∂u
= f'(u^2 - v^2) * 2u
Partial Derivative with respect to v:
Similarly, to find ∂g/∂v, we differentiate g with respect to v treating u as a constant. Using the chain rule, we get:
∂g/∂v = ∂f/∂x * ∂(u^2 - v^2)/∂v
= f'(u^2 - v^2) * (-2v)
Twice Differentiable Function:
Since f is given to be twice differentiable, this implies that f'(u^2 - v^2) is also differentiable, which allows us to find the second-order partial derivatives of g.
Therefore, the correct answer is a) f'(u^2 - v^2) * 2u and f'(u^2 - v^2) * (-2v) for ∂g/∂u and ∂g/∂v respectively.
