Error Propagation

  1. Sep 15, 2004 #1
    Hi all.

    well, I'm geting problems when trying to calculate the absolute error of an average velocity. I've got a graphic of points generated by a sensor which scans an object position everey 0.05 seconds. concretely i need to calculate the average velocity between two points, at first two nearby points and then two further points. heretofore there is no inconvenient, but when i try on estimating the error by using partial derivates... I'm sure that something is wrong, because the further points give me a smaller error.

    How can I do to estimate ther error of the average Velocity expresed by (x2 - x1) / (t2 - t1)?

    thanks

    PD: excuse my english, but there's not good forums in my language. :biggrin:
