Sir, why in today's quiz the ans of that piecewise unit step function is same as Laplace of 1?? If we write the function in unit function representation i.e u(t-(n-1))-u(t-n) it Laplace change for different values of n. is it correct sir??c

Why must we do u(t-a), if we start at a point "a" cant we just define u(t) at that point? Or is it because a unit step function u(t) is universally defined at 0?

But when you change your point a then u(t) might create confusion. Hence as a standard practice we write u(t-a) and we specify what is a

at 10:17 if t >4, for example 5. I'm not getting as the output. 3[(u(3)-u(1)] +9 [(u(-1)-u(-2)] = 3[u(3)] = 3 P.S - found the answer , when we express u(t-2), that means for t >2 the function's output is 1

How to find the Laplace transform of tan-1 t

@farehamaryum5388

Жыл бұрын

Bcz something auxiliary function bnty

@DrMathaholic

Жыл бұрын

Answer involves cosine and sine integral functions.. Using laplace of derivative: L{f'}=sL{f} -f(0) we get, L{1/1+t^2}= s L{ tan -1 t} -0 So L of tan inverse t = 1/s * L{1/1+t^2}... Now laplace of right side involves sine and cosine integral function.. Try the calculator:: LaplaceTransform[Arctan[t],t,s]" into the input field at www.wolframalpha.com

If you express it as 8 * u(t-2) + 6*u(t-2) then for t>2 , u(t-2)=1 so we get 8+6 instead of only 6.
