    Thevenin Resistance Homework: Find max Power Transferred & Delivered

    Okay. I think I got it. Now, using KCL at the node above the dependent current source I have: 0 = 4 - 3_i_1 - i_1 4 = 4_i_1 \ldots i_1 = 1 amp V_{oc} = 5 V \ldots V_T = 5 V I_{sc} = 4 A R_{th} = \frac{V_{oc}}{I_{sc}} R_{th} = \frac{5}{4} \Omega So, a voltage source of 5V...

    Non-homogeneous 2nd order diff eq involves power series

    I just need a hint or something to see where I start. I'm at a loss for a beginning. Consider the non-homogenous equation y'' + xy' + y = x^2 +2x +1 Find the power series solution about x=0 of the equation and express your answer in the form: y=a_0 y_1 + a_1 y_2 + y_p where a_0 and...

    How Can Laplace Transforms Solve an Initial Value Problem?

    I appreciate the help :smile: thanks. I can't believe I didn't see that the antitransform was so simple... y(t) = 1 + 3t^2

    How Can Laplace Transforms Solve an Initial Value Problem?

    I have looked all over the internet and in my book and I cannot find the above mentioned Laplace Transform formula anywhere. Did you mean (n!) in the numerator vice the (n+1) ? In that case, that would make my answer 3t^2

    How Can Laplace Transforms Solve an Initial Value Problem?

    Yes this is where I was lost because I didn't have that in the table my professor gave me. His said: L\{t^n\}=\frac{\Gamma(n!)}{s^{n+1}} I am lost because I only see this problem as: L\{t^n\}=\frac{\Gamma(2+1)}{s^{2+1}} = t^2... i know this isn't right. wait... is this what I...

    Laplace Transform With Initial Values

    Okay, I know this is alot... but I am stuck, so here goes... Use the method of Laplace transform to solve the initial value problem y''+3ty'-6y=0, y(0) = 1, y'(0) = 0 L\{y'' + 3ty' - 6y\} = L\{0\} s^{2}Y(s) - sy(0) - y'(0) + 3L\{ty'\} - 6Y(s) = 0 s^{2}Y(s) - s(1) - 0 -...
