為什麼這時積分變數t變換為τ時，積分範圍不會改變呢

例題1-7: Given a function f(t) and its Laplace transform F(s), what is the Laplace transform of the delayed version of f(t) by 2>0 units of time, i.e., f(t−2)? You must give a +b(1) proof of your answer. 解 根據拉氏轉換的定義,F(s)=L[f(t)]=ff(t)e="d,所以 【85 中興電機】 [ƒ (1-2)] = f(t−2) e™ dt = f(t-2)e(-) d(-2) -2s 【大專告 201 0 0 C-TER -λs (a)D -ST =eft-)e-d(1-2) = e | f(t)e dt = eF(s) 0

求這題詳解（鉛筆部分也是題目）
