F s 1/s s+1 拉氏反变换

Weby 2 /f = y 1 /(s 1-f). Rearranging and using our definition of magnification, we find. y 2 /y 1 = s 2 /s 1 = f/(s 1-f). Rearranging one more time, we finally arrive at. 1/f = 1/s 1 + 1/s 2. This is the Gaussian lens equation. This equation provides the fundamental relation between the focal length of the lens and the size of the optical system. WebDec 30, 2024 · Find the inverse Laplace transform of. F(s) = 3s + 2 s2 − 3s + 2. Solution. ( Method 1) Factoring the denominator in Equation 8.2.1 yields. F(s) = 3s + 2 (s − 1)(s − 2). The form for the partial fraction expansion is. 3s + 2 (s − 1)(s − 2) = A s − 1 + B s − 2. Multiplying this by (s − 1)(s − 2) yields.
