Rewriting a piecewise function using step functions

Click For Summary
SUMMARY

The discussion focuses on rewriting the piecewise function f(t) = exp(c*t) for 0 <= t < 2 and f(t) = 0 for t >= 2 using step functions. The proposed transformation is f(t) = exp(at)*[H(t-0) - H(t-2)], where H represents the Heaviside function. The key question raised is determining the value of 'a' in this context. It is noted that the function is not defined for t < 0, which is an important consideration in the transformation.

TL;DR
Function properties
Suppose we have a piecewise function

f(t) = exp(c*t) when 0 <= t < 2 and f(t) = 0 when t >= 2.

Can the above be rewritten as

f(t)= exp(at)*[H(t-0) - H(t-2)],

H is a heaviside function.
