The Laplace transform will convert the equation from a differential equation in time to an algebraic (no derivatives) equation, where the new independent variable s is the frequency. We can think of the Laplace transform as a black box. It eats functions and spits out functions in a new variable.

We use t as the independent variable for f because in applications the Laplace transform is usually applied to functions of time. The Laplace transform can be viewed as an operator L that transforms the function f = f(t) into the function F = F(s). Thus, Equation 13.1.2 can be expressed as. F = L(f).Thus, the solution of the differential equation y(t) is such that its Laplace transform is \displaystyle Y(s)=\frac{1}{s(s-1)} However, we realize we are not able to find in the table any function that satisfies it. The idea is to turn Y(s) into a sum/difference of two (or more) functions. To do so, we decompose it into partial fractions.Discover how a pre-meeting survey can save time, reduce the sales cycle, and make for happier buyers.
