    Node-Voltage Method to Solve Circuit Problem

    Actually I tried a few ways of calculation but this is one of them.. Node 1 : V1/2+(V1-V2)/8+(V1-V3)/16=0 Node 2 : (V2-V1)/8+V2/3+(V2-V3)/24=0 Node 3 : (V3-V2)/24+V3/3+(V3-V1)/16=0 Then I calculated it using the calculator and got V1=V2=V3=0. Another way I tried, calculating using...

    Node-Voltage Method to Solve Circuit Problem

    http://img106.imageshack.us/my.php?image=hahaxp4.jpg I'm required to use the node-voltage method to obtain the branch currents at all the resistors. I already tried using the node-voltage method at the three middle nodes but I still couldn't get the currents as obtained using OrCAD. I...

    Solve Calculus Assignment: Show x^3 - 3kx + 1 ≠ 0 & Find Discontinuity of u(x)

    Thanks Ivy, I think I kinda got the idea of how to solve the first question.. About the 2nd one, I'm not sure what's unit step function, my lecturer has never mentioned it, even my friends r not sure about it..That's y I'm not sure how to approach the question when it comes to dealing with...

    Solve Calculus Assignment: Show x^3 - 3kx + 1 ≠ 0 & Find Discontinuity of u(x)

    I'm aware of those criterias, but I'm still not sure how to show that it doesn't have 2 distinct roots..

    Solve Calculus Assignment: Show x^3 - 3kx + 1 ≠ 0 & Find Discontinuity of u(x)

    1.Show that x^3 - 3kx + 1 = 0 does not have two distinct roots when k<0 2.Locate the points of discontinuity for the functions : a.) f(x)= 2u(x-3)-u(x-4) b.) g(x)= [u(x)-u(x-pie/2) u(x) is a unit step function. Could u guys help me out, I have no idea how to solve this..
