Best ResponseYou've already chosen the best response.0just to be clear, we can represent this as X(t)=u(t)+2u(t1)

Best ResponseYou've already chosen the best response.2yeah what u want to do is actually u(t) + u(t1)

Best ResponseYou've already chosen the best response.0has constant feed rate of 10m^3/min (theoretically) but at time t=0, a disturbance pushes 1m^3 of water into the tank and an extra 2m^3 of water at t=1min (So an additional 1m^3 of water per min)

Best ResponseYou've already chosen the best response.2okay lemme get this right though u want 10 before 0?

Best ResponseYou've already chosen the best response.2u know for laplace transform it cuts off the part before 0

Best ResponseYou've already chosen the best response.2because if u look at the power series summation n from 0 to inf x^n this only converges when x<1

Best ResponseYou've already chosen the best response.0yea, they draw these graphs just to show use the theoretical flow regime. yes it cuts off at 0 for laplacing, but we have questions that show graphs like these.

Best ResponseYou've already chosen the best response.0they have function X(t)=90(u(t)u(t0.1))

Best ResponseYou've already chosen the best response.0so pretty much i just applied it to get X(t)=11u(t)+12u(t1) but need confirmation

Best ResponseYou've already chosen the best response.211u(t)+12u(t1) that wont give u that

Best ResponseYou've already chosen the best response.0i just need to find this function as step function

anonymous

Best ResponseYou've already chosen the best response.0so i can solve this silly problem

Best ResponseYou've already chosen the best response.0how about 10(u(t)+2u(t1))?

Best ResponseYou've already chosen the best response.2maybe they just dont want to cover the 10, what they have there is

anonymous

Best ResponseYou've already chosen the best response.0perhaps they just shift it down so its just normalises it

Best ResponseYou've already chosen the best response.0would be X(s)=10u(t)+11u(t1)

anonymous

Best ResponseYou've already chosen the best response.0why isn't it 11u(t1)? aren't we increasing an addition m^3 after t=1min

anonymous

Best ResponseYou've already chosen the best response.0yeah cause your steady state value is still at 10

Best ResponseYou've already chosen the best response.03weeks of lapalce transforms and its a subject inside this course, i rekn I'm doing well to grasp a lot of things haha

Best ResponseYou've already chosen the best response.2i think laplace transforms might be a waste of time

Best ResponseYou've already chosen the best response.2its to introduce u to fourier transforms

anonymous

Best ResponseYou've already chosen the best response.0lel, we use lapalce transforms in process control so its easier to solve differential equations (approximate it using linearisation)

dan815

Best ResponseYou've already chosen the best response.2ye but eventually DE become too hard with laplace, so u gotta use fourier transforms for PDES

Best ResponseYou've already chosen the best response.0yeah tru dat but that was for eng math. i guess we aren't looking at too hard of ODE's but i guess they teach us this smack and we have to learn their way of calculating there questions
