Laplace transformation of f(t) = e^(at)

Click For Summary
SUMMARY

The Laplace transformation of the function f(t) = e^(at) for t > 0 is defined under specific conditions. The integral diverges if the parameter s is less than the constant a, indicating that the Laplace transform does not exist in this case. Therefore, for the Laplace transform to be valid, it is essential that s > a. This highlights the importance of understanding the conditions for the existence of the Laplace transform in relation to the function's parameters.

for this question:
f(t)=e^(at), when t>0, a is constant. find the laplace transformation.

my question:
for the integration part, what happens if s-a<0?
 
Physics news on Phys.org
If s < a then the integral diverges. There are conditions on f(t) for the existence of the transform.
 
thank you very much!
