    Axiomatic set theory ZFC is inconsistent thus mathematics ends in contradiction

    Axiomatic set theory ZFC is inconsistent, thus mathematics ends in contradiction: http://gamahucherpress.yellowgum.com/wp-content/uploads/MATHEMATICS.pdf Axiomatic set theory ZFC was in part developed to rid mathematics of its paradoxes, such as Russell's paradox. The axiom in ZFC developed...

    My Graphing Calculator Gave Me Inconsistent Answers

    I made up the function y = x^4 - 3x and looked for it's minimum. My graphing calculator said the minimum was at x = 0.90855953 (and I know this is rounded, not exact). I set the derivative = 0, solved that equation for x, and got 0.908560294 (and I know this is rounded, not exact). The two...

    Show the scheme is inconsistent

    Scheme for u_t = u_{xx}: u_j^{n+1}= (1-2\alpha - 2\beta)u_j^n + \alpha(u_{j+1}^n + u_{j-1}^n) + \beta(u_{j+2}^n + u_{j-2}^n) Denote \mu = \Delta t/(\Delta x)^2. Show that when \mu is a constant, that the scheme is inconsistent unless \alpha + 4\beta = \mu Show that the scheme is four-order...

    Influence of inconsistent initial values on time integration

    Hello everybody, I was wondering whether someone has more information on the influence of inconsistant initial conditions on solving a system of ODE's with periodic solutions using a time marching method like a 4th order Runge-Kutta scheme. The phenomenon I am studying is described by a system...
