SUMMARY

The discussion focuses on applying the Laplace transform to a non-homogeneous equation, specifically one represented as Aekt. The key steps involve transforming the left-hand side (LHS) and recognizing that it must include the right-hand side (RHS) to solve for Y(s). The transformation yields the equation f(s)Y(s) = A/(s-k), leading to Y(s) = A/f(s)(s-k). Finally, the inverse Laplace transform is applied to retrieve the original function y(t).

Homework Statement


do a laplace transform on a given non homogeneous equation.
to eventually find out y

Homework Equations


i don't think the equation is needed. however this non homogeneous equation is equal to Ae^kt


The Attempt at a Solution


well. i applied the laplace to the LHS. with all the '' and ' and stuff. but i didnt incorporate the RHS. can it just be equal to the Laplace of that side? I am thinking yes but not sure.
also, pretty baffled as to how that gives the original y.

You'd need to apply the laplace of the RHS.

The LHS would have some function in s multiplied by Y(s).

so

f(s) Y(s) = A/(s-k) as the transform of Ae^kt is A/(s-k)

Y(s) = A/f(s)(s-k)

then you apply the inverse laplace transform on both sides. The LHS becomes y(t), the original y.
