The inverse Laplace transform of the function f(S) = 1/S (1 + S) is_________________?
Correct answer: D. 1 - e-t
- A. 1 + et
- B. 1 - et
- C. 1 + e-t
- D. 1 - e-t
Explanation
Interpreting the expression as 1/[s(1+s)], partial fractions give 1/s − 1/(s+1), whose inverse transform is 1 − e⁻ᵗ. The printed parentheses are incomplete, but the answer choices clearly indicate this intended form.
