If f (x) f ( x) is a given function, then the inverse of the function is calculated by interchanging the variables and expressing x as a function of y i.e. x = f (y) x = f ( y).

What Sal introduced here in this video, is a method that was 'woven' specially for finding inverse of a 2x2 matrix but it comes from a more general formula for determining inverse of any nxn matrix A which is: A⁻¹ = 1/det (A) * adj (A) where adj (A) - adjugate of A - is just the transpose of cofactor matrix Cᵀ. To solve differential equations with the Laplace transform, we must be able to obtain \(f\) from its transform \(F\). There’s a formula for doing this, but we can’t use it because it requires the theory of functions of a complex variable. Fortunately, we can use the table of Laplace transforms to find inverse transforms that we’ll need.Sep 29, 2022 ...
