英:[lɑ:ˈplɑ:s trænsˈfɔ:m] 美:[ləˈples trænsˈfɔrm] Laplace transform是什么意思 拉普拉斯变换,拉普拉斯变换式 Laplace transform英英释义 noun a transformation of a function f(x) into the function {latex}g(t) = \int_{o}^{\infty}{e^{-xt}f(x)dx}{/latex}...
Evaluating Laplace Transforms, we will be using the following formulae L(cos(at))(s)=ss2+a2(∗)L(tnf(t))(s)=(−1)ndndsn[L(f(t))(s)](∗∗) Laplace transform is a linear transformation, meaning L(f(t)+g(t))=L(f(t))+L(g(t)). ...
This chapter discusses the basic properties of Laplace transformation. The Laplace transform of the function f ( x ) , denoted by F ( s ) , is defined as the improper integral F ( s ) = ∫∞ 0 f ( x )e -sx dx. The functions f ( x ) and F ( s ) are called a Laplace ...

The inverse Laplace transform is the transformation of a Laplace transform into a function of time. If L{f(t)}=F(s) then f(t) is the inverse Laplace transform of F(s), the inverse being written as: [13]f(t)=L−1{F(s)} The inverse can generally be obtained by using standard...
The inverse Laplace transformation of a function {eq}F(s) {/eq} is a function {eq}f(t) {/eq}. It is a method of converting a function from s-domain to t-domain. The notation that we are used for denoting the inverse Laplace transform is {eq}...
