No one has been there for me like you have

[birhanuworku]

this is unpresdented explanation.thank you sir/dir

[ДмитрийШушпанов-лф]

Great!!! If we take Laplace transform of unit step function of other function (cos(x) for example)?

[ryangray]

How does the third case change if we have something like:

(4t+20)*[u(t+4)-u(t+2)]

Thanks
