    Rate of Change

    Hi! As a part of a mathematical construction I used the rate of change of F(s) with s, i.e. dF/ds. F and s are smooth functions. The problem is that s(u,v,w) is a function of u, v & w and actually I need to find the rate of change of F with respect to u, v & w. The question is: what does...

    Linear homoheneous ODE question

    Homework Statement y'' + p(x)y' + q(x)y = 0 p(x), q(x) continuous for x = (-1,1) Homework Equations I. prove that if y1 is an answer to the ODE and y1(0) = y'1(0) = 0. then: y1 = 0 for all x = (-1,1). II. if y1 is an answer to the ODE, how would you find the second non-dependent...
