Hi this question is asking to show how multiplying the brackets of the first equation can result into the second equation, I think I have been looking at it for far to long as I can not seem to work it out. any pointers would be much appreciated.

Thanks for the Wikipedia info just seen the table which includes a lot more Laplace transforms than the info provided in the workbook. Looking at this it looks something like 3 x e-3t cos wt any further advice would be much appreciated as I believe I may have wasted a lot of time on this...

The question is asking for the inverse Laplace transform of the equation using the table of Laplace transforms, all the ones completed in the workbook at not of this format so difficult to find a similar method to calculate. I have posted the question where you recommended, thank you for your help.

Homework Statement Determine the inverse Laplace transform Homework Equations 3s+9. (s+3)^2+7 The Attempt at a Solution [/B] Hi iam new to the forum and still unsure how to make the equations the correct format so hope you can understand what I have typed. I have Tried to Convert...

Sorry not posted many threads and not familiar with the way you have written the equation so well. The last equation. 3s + 9. (s+3)^2+7

Homework Statement Determine the inverse Laplace transform Homework Equations 3s+9/(s+3)^2+7 The Attempt at a Solution Converted to 3s+9/s^2+6s+16 to try and use the partial fractions method but getting nowhere. I'm Not sure if Iam making the question more difficult, can't seem to put the...

Homework Statement b) state by inspection (i.e. without performing any formal analysis) all you can about each of the periodic waveforms shown in FIGURE 1 in terms of their Fourier series when analysed about t = 0 Homework Equations 3. The Attempt at a Solution Hi could someone please be...

Hi Matt, I only handed the assignment In last Saturday so have just checked if I have yet received any response and I have. it has been highlighted that I have made a sign error and it should have been a minus so you are probably correct. I have just recalculated my equation and the result I now...

Thank you rude man for the very fast response, I keep doubting the answers I'm getting and keep trying to find ways to double check my results. I will continue with the assignment and hopefully get it completed soon. cheers

hi wanted to put this on as a new post but not sure how so thought it best to place with relevant question (b) A 50Ω lossless transmission line of length 0.4λ is terminated in a load of (40 + j30)Ω. determine, using the equation given below, the input impedance to the line. I have...

Hi thank you for fast response and sorry for double posting, I checked my re arrangement as you suggested and it was incorrect. I have had some further feedback and been advised that the calculation to find RS is RS = [ R'P - RP ] * n^2 with this I will hopefully complete the question.

hi i am new to the forum and trying to complete the electrical and electronic engineering course but the learning material provided does not seem to provide adequate knowledge to complete some of the questions being asked. I rearranged the formula R'P = RP + n^2 * RS to RS = R'P / (RP + n^2)...
