I have this theory that when two people interact, one dominates the experience while the other is passive. You see it all the time. I suspect these suttle breaths are to insure that the speaker is dominating the experience. The you and I, here creating this moment together, type of experience...

So I've been watching a lot of videos on speaking and communication recently because I want to be an effective speaker and communicator in everyday life and interaction with other people. I've mostly focused on observing important political figures (Presidents, Senators, Royal Family etc.)...

Hi, I would like to find the inverse Laplace transform for 11/(s^2+16)^2 I have tried to expand it using the following partial fraction decomp to find the constants and take the inverse Laplace but this did not work C1(s)+ C2/(s^2+16) + C3(s)+C4/(s^2+16)^2 Does anyone have any suggestions?

Does anyone know how to find the constants If you had F(s)= 1 / ((s)^2+16)^2 ? I need to find the inverse laplace transform of F(s)

I found a better table, this post can be deleted

Homework Statement Find: Inverse Laplace for x(t)= (e)^-5t*(t)^4 using laplace table and laplace properties. Homework Equations The Attempt at a Solution Well, I have been working on this problem for a few days now and cannot seem to figure it out. The two functions are not...

Thanks for your reply Vickson, but to be honest I have no idea how to understand that as of right now...how would you recommend I tackle this problem to find the inverse laplace to get the function back to the time domain?

Thanks for all the help, let me ask you guys this, If you had F(s)=1/((s)^2+16)^2 could you expand it like so to find your constants [ (c1(s)+c2) / ((s)^2+16)] + [(c3(s)+c4) / ((s)^2+16)^2]

Nevermind we got it. It's simply 20/7(s/s^2+3^2) which is 20/7cos(3t)...do you agree?

Ok, so I expanded it like this c1/2 + c2/s + (c3(s)+c4)/(s^2+9) got my system of eqs got my constants c1=0 c2=-20/7 c3=20/7 c4=0 so -20/7*(1/s) --> L^-1[ -20/7*(1/s) ] = -20/7*Us(t) from table but I am a little unsure how to find inverse laplace for the next term...

Homework Statement Hi I would like to know how to expand 20/2s(s^2+9) in order to find the inverse Laplace Transform of the function K(s) to gt k(t). The (s^2+9) term in the denominator is throwing my calculations off for the constants because of the s^2 term. Homework Equations...

Hello, I have a relatively simple question. after being unable to find it through google I have decided to ask you guys if you know what the Laplace transform of a unit step function that looks like this would look like Us(t-2) From tables, the Laplace transform for a regular units step...

Thanks

I don't think you realize what I am asking. Hopefully this will clarify my question even further. As you imply in your statement Sin(0) is 0 because if you look at the coordinate (0,1) and "take the sin" you get 0 which is the y coordinate. My question is WHY does "taking the sin" of this...

I guess what I am asking is why is sin defined as the y coordinate?
