Homework Help: How to do this question?

  1. Aug 17, 2008 #1
    ive encountered xdot and x questions before but never one writen in this dx/dt format so i dont know what to do?

    given the first order differential equation dx/dt=x2 -3x-10 find the equlibrium points in the x--xdot plane and draw the trajectory in the plane indicate the time directions and discuss the natures of the equlibrium points
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution

    If I tell you that dx/dt and [itex]\dot x[/itex] are just different notation for the same thing, can you do it then?

    i can ye lol, is Xdot just distance in relation to time then?

    and are you refering to dx/dt=xdot or xdot dot

    usually xdotdot is acceleration
    and xdot is velocity
    so xdot: dx/dt
    xdotdot : d2x/dt2
