Thread: complex numbers, taylor series, vectors, Euler's theorem and limits

Hey guys, got a few questions on calculus that i need help on you can just help on the ones you know.

MACLAURIN AND TAYLOR SERIES:
1). find the nth term of Maclaurin series for the function xsin3s

b). find the taylor series expansion, up to and incl. powers of 2 for the function e^xy^2 about (1,2)

This question is not very clear. I assume that you want to know the following.
“What is the measure of the angle between the consecutive roots of ?”
That is easy:

Did you read the "sticky", "rules for posting..."?

You should not post more than 2 questions in a thread (and you have from 5 to 10 depending on how you count distinct "questions").

And you certainly should not just post questions without any indication as to what you have tried yourself!

I'm very sorry, I didnt read it no, I knew it was too good to be true to post up all them questions in one thread and by any luck get all the answers back, I could've started like 5 threads though, but I thought its better if I put them all in one, incase you know, I get told off. Uhm, its out of desperation that I posted all them questions up without showing I have tried to work any of them out because, all the ones I've worked out are like, wrong so I thought if I turn to a forum then I might get the answer I need, but obviously, I've tried to work it out myself, but haven't any luck, thats why I'm here, . But uhm sorry again for the 5-10 or more questions posted here, for future reference should I have started 5 different threads?
