 Corrections:
+Section 1.7 question (iv)
+-> e^(-2t) must be squared before performing the integration when calculating the energy of the signal.
-Section 1.7 question (iv)
+-> The correct final answer for the energy should be 1/4
--> e^(-2t) must be squared before performing the integration when
-calculating the energy of the signal.
--> The correct final answer for the energy should be 1/4
-Section 1.8 question (i)
--> The correct formula is used in the solution (i.e. (A^2)/2 + (B^2)/2 but
-the final answer is wrong)
--> Final answer should be: ((1/2)^2)/2 + ((1/2)^2)/2 = 1/8 + 1/8 = 1/4
-Section 1.8 question (v)
+Section 1.8 question (i)
--> 2^k must be squared before performing the summation when calculating the
-energy of the signal.
+-> The correct formula is used in the solution (i.e. (A^2)/2 + (B^2)/2 but the final answer
--> The correct final answer for the energy should be 1,398,106
+is wrong)
+-> Final answer should be: %%((%%1/2)^2)/2 + %%((%%1/2)^2)/2 = 1/8 + 1/8 = 1/4

 Section 1.15 question(i)
--> The original question should be: x[k] = sin(4k) + cos((2pi*k)/(3))
+-> The original question should be: x[k] = sin(4k) + cos%%((%%2pi*k)%%/(%%3))
