    Inverse matrix using Hotelling Approximation

    that is quite odd. Looks like a nice read. I'll be sure to post any problems. Thanks one million John.

    Inverse matrix using Hotelling Approximation

    Hello all, I am taking a Numeric Methods course this semester and my professor asked us to investigate Harold Hotelling's method( I suppose this would be and approximation) of finding the inverse of a matrix. I have searched for day and have found many cool things linked to Hotteling but...

    Engineering Help with home work question, RL circuit

    Sorry about that. I didn't use a circuit schematic program to draw the circuit. I actually labelled them. I was hoping that would be sufficient. I solved the question yesterday one hour before the class. I will post the solution and a proper diagram shortly.

    Engineering Help with home work question, RL circuit

    Ok, i am thinking i1=i-(4v/5ohms). Note i got the 4 volts( which is supplied by the independent voltage source) from the scalar function vf, when evaluated in the range 0<t<1.8.

    is there any simple way of calculating i1 in the circuit, that would make things a lot easier.

    Engineering Help with home work question, RL circuit

    vf= 4(u(t)-u(t-1.8))v I have to find i(t), for the attached circuit. I already evaluated it for t<0. But i a having problems in the rage 0<t<1.8. I am at the point where i have to find the forced response, so o let t tend to infinity (t->infinity). And so the Inductor acts like a short...
