Question
Consider the following piecewise function: (image 1)
 
Determine which of the following expressions is equivalent to the given function. (image 2)
sen(t); 0 <t< n/2
f(t) = { cos(t); T/2<t<n
Transcribed Image Text:sen(t); 0 <t< n/2 f(t) = { cos(t); T/2<t<n
a. sen(t)U(t – 1/2) + cos(t)U(t – 1/2) + e'U(t – x)
b. sen(t) – sen(t)U(t – 7/2) + cos(t)U(t – 1/2) – cos(t)U(t – 7) +eU(t – n)
c. sen(t) + cos(t)U(t – n/2) +e'U(t – a)
d. sen(t) – sen(t)U(t – 7/2) + cos(t)U(t – 7/2) – cos(t)U(t – 7) + eU(t – a) – e'
