Transcribed Image Text:Question 4.
The function f(t) is defined by
0 < t < 2
f(t) = {
2 < t < 5
-2t+4
-6
with f(t+5) = f(t) .
Evaluate f(-4.4), ƒ(0), ƒ(5.5), ƒ(7.8) and state the value that the Fourier series, FS(t), of f(t) would converge to at t = 0, 0.7, 2, 5.
Enter all your answers correct to one decimal place.
• A: Enter f(-4.4):
• B: Enter f(0):
• C: Enter f(5.5):
• D: Enter f(7.8):
E: Enter FS(0):
