Splet07. maj 2016 · Explanation: Partial fractions of 1 (s +1)2 will be of type. 1 (s + 1)2 = A s +1 + B (s + 1)2. = A(s +1) + B (s + a)2. or 1 (s +1)2 = As + A+ B (s + a)2. Equating coefficients of numerator, we have A = 0 and A +B = 1 or B = 1. Hence 1 (s + 1)2 = 0 s +1 + 1 (s + 1)2. or 1 (s +1)2 = 1 (s +1)2. It is apparent that 1 (s + 1)2 is already in its ...
Splet2. Leave the e − s alone. We see. e − s s ( s + 1) = e − s ( 1 s ( s + 1)) = e − s ( 1 s − 1 s + 1) = e − s s − e − s s + 1. Now you can take the inverse transform of the two terms separately.
