Sample Question #96 (mathematics – basic calculus)
Let both f(x) and g(x) be continuously differentiable in x. Find the 1st derivatives of the following functions.
(1) h(x) = f(x) + g(x)
(2) j(x) = f(x) * g(x)
(3) k(x) = f(x) / g(x)
(Comment: calculus is pretty fundamental in everything quants do, so it’s always important to remember your basic calculus)
