Homework Statement
suppose that (s_n) and (t_n) are sequences in which abs(s_n)≤t_n for all n and let lim(t_n)=0. Prove that lim (s_n)=0.
The Attempt at a Solution
I find absolute values to be really sketchy to work with I'm really in the dark if this is at all correct:
Let ε>0 be given, then...
find the irreducible quadratic factors of z^(4)+4
The Attempt at a Solution
Im stumped...this is all I've got:
[(z^(2))^2]-[(2i)^2]
(z^(2)-2i)(z^2+2i)
Any guidance is greatly appreciated!
What if when I'm finding the repeated terms from integrating the vector field with respect to x and then y, i come across two terms that are same except one is negative and the other positive. What does that mean, and how do i represent that in the overall potential function I'm finding?
Just out of curiosity, I'm wondering if anybody else experiences this when taking University science and math courses:
Unlike some of my peers, I usually gain nothing from lectures (there are exceptions with phenom professors). In order for me to retain information I need to make complete of...
