-====== General ======
+----
+**Assignment 1:**
-===== Do I need to register for a CSE Computer Account? =====
+__Problem 5(d):__ Any hints for this question?  I know we can use Euler's formula to express sin(x)as [e^(jx) - e^(-jx)] / 2.
+Is this what you're looking for?
-Yes.
+Answer: This is one way of solving the summation. You can follow this approach.
-===== Do I need to attend class? =====
+__Problem 7:__ What do you mean by "analytically"?  Does this mean, using the DTFT tables?
-If you wish to pass.
+Answer: Analytically implies using the definition of the DTFT and solving the summation.
-====== Tests ======
+__Problem 8:__ You want us to take the DTFT of both x[k] and h[k] to obtain X(e^jw) and H(e^jw), multiply them together, then take the inverse DTFT?
-===== Do I need to write all tests? =====
+Answer: Absolutely.
+__Problem 10:__ You want us to take the z-transform of both x[k] and h[k] to obtain X(z) and H(z), multiply them together, then take the inverse z-transform?
+Answer: Absolutely.
