What is the Laplace transform of 1 by T?
In general the Laplace transform of tn is Γ(n+1)sn+1, and Γ(n) isn't defined on 0,−1,−2,−3... This integral is the definition of the Laplace transform, so the transform doesn't exist if the integral doesn't.
What is the Laplace of 1?
The Laplace transforms of particular forms of such signals are: A unit step input which starts at a time t=0 and rises to the constant value 1 has a Laplace transform of 1/s. A unit impulse input which starts at a time t=0 and rises to the value 1 has a Laplace transform of 1.
What is the Laplace transform of cos 3t?
From the formulas, L[cos(3t)] = s s2 + 9 . So, by s-shift, F(s) = L[e-t cos(3t)] = s + 1 (s + 1)2 + 9 . (b) Compute the derivative f/(t) and its Laplace transform.
