Given that 0 < a < b, let f(t) = 1 if a t < b, f(t) = 0 if either t < a or t b. First
Chapter 4, Problem 4.1.38(choose chapter or problem)
Given that 0 < a < b, let f(t) = 1 if a t < b, f(t) = 0 if either t < a or t b. First, sketch the graph of the function f, making clear its values at t = a and t = b. Then express f in terms of unit step functions to show that (f(t)} = sl (e-as - e-bs).
