    Financial Mathematics Question

    By considering the functions x(e^\frac{\delta}{x} - 1) and x(1-e^\frac{-\delta}{x}) and their derivatives with respect to x for x \geq 1 and \delta > 0 show that i^{(p)} > i^{(p+1)} and d^{(p+1)} > d^{(p)} when p is an integer greater than zero.

    I'm sorry, are these two functions of x supposed to be i and d, respectively? And just to clarify, is i^(p) the pth power of i or the pth derivative?
