Thanks. Regarding #2, I got: Where to from here?
Let Edit: Sorry, I had a typo in my first post. Should've been iy instead of ix using the sub here.
You should know . That is the standard definition for the complex sine function. Then it is easy to see:
Thanks, I think I got the result: (1) But...for (1), how does that equate to if it contains the imaginary part ? (I thought only dealt with imaginary parts, given the 's in its definition). Also, trying to obtain : Is that correct?
No. Try reading over our posts again. Here, we let to get:
Thanks I get it now.
