ahhh cool now let's say I have (t-1)^4 u(t) function is 1 from 0 < t < 1 and (t-1)^4 for t> 1 I can easily do the transform of t^4 how would i play with it to just do a time shift after the transform or do I have to go the integral route and do parts?

Homework Statement find the transform of sin (wt) u(t - b) I have to get it into the form for the time shift but I do not know how to deal with the unit function help appreciated

Thanks, I am kinda getting the idea The way I saw it done was dividing 1442 /3 for base 6 to base 3 but the numbers do not match probably and for 112022 is by dividing by 20 (number 6 in base 3) I'm missing the counting technique when dividing or just suck at itThis is basicly what he has...

Homework Statement How do you change a base into another number directly without changing to base 10 or base 2 for example? Eg changing 1442 base 6 to base 3 = 112022 Just want to know the steps in the division Teacher wants us to do it this way for less error Help appreciated

I know the answer is 20e^(-5t) by just taking the 1/10 out from the v(t), and the k on top of the exponential is negative 10/2 but I don't know the solving mechanismMy calc book only has one example and it is when it equals a function and not a constant in the first equation, so I can just...

Homework Statement How would you solve 2=\frac{v(t)}{10}+\frac{\int{v(t)}}2 Thanks for your help

Homework Statement Trying to write -8\pi - 8\pi\sqrt3 j in exponential I got the coefficient as 16 pi but to get the theta in top of the exponential I have to do the inverse tangent of \frac{-8\pi} {-8\pi\sqrt3 j} I know it is pi over 3, but what is the easiest...

Ahhh cool Now I get it TA probably thought all resistances were equal and confused me more

For this one the TA said that R2 R4 are in series and R3 R5 are in series, and R24 in parallel with R35She explained it as R2 R4 having the same current, same as R3 R5 and drew it like this _________________ | | | R2 | R3 |___a | | | | b__| |...

Thanks a lot man, still not so obvious to me

What is the approach for that other problem? And also for this one Sorry, but I really want to master these diagonal circuits :) |------------* | / \ | R2 R3 | / \ |...

if I had a circuit like this a------------* / \ R2 R3 / \ *-------* \ / R4 R5 \ /...

nm finally got itThe R23 is in parallel and then in series with the R1 R45 are in parallel and also in parallel with R123 Problem is it was by trial and error, if I get another circuit with diagonals I would probably miss it in a test

R23 and R45 are both in parallel right? R23= (20)(30)/(50) R45(60*40)/100 I tried them in series too, what I want to understand is how to deduce the pathways for the current in circuits like this one. Diagonals seem to mess me up Edit do I have to do a wye delta conversion?

Homework Statement Edit Circuit looks messed up, if you can quote me you can see the text of the circuit This is how the circuit looks*--------------------* | / \ | R2 R3 R1 / \ | *-------...
