A function g(t) has the following description. It is zero for t < ? 5. It has a slope of –2 in the range ? 5 < t < ?2. It has the shape of a sine wave of unit amplitude and with a frequency of 1/4 Hz plus a constant in the range ? 2 < t < 2. For t > 2 it decays exponentially toward zero with a time constant of 2 seconds. It is continuous everywhere.
