New to the forum and have a maths assignment where I'm struggling to do a few of the questions, most notably the maths relationship questions and summation notation. Any help, steps or advice including reading material would be appreciated.
Questions struggling with:
Doing this course after not doing this math in High School and slowly trying to pick up on it, from my understanding my min is 1/2 and max is 3/4 and it's going up by n over (N+1!) so they're just wanting me to draw the sigma symbol and put those three numbers in?
Likewise second one?
I believe I've gotten the first three, but I'm struggling to get my head around understanding questions like number 5,6,7.
Edit: Thought I'd edit it what I've tried to do. I'm tried re-writing it out so for example number one was Z+ (positive integers) belong to subset of Q. Are all integers rational, yes. Etc. My simplying only seemed to work for first three than I struggled to get my head around the others.
Follows on from struggling to understand the relationship.
Thanks any help is much appreciated.
