why the set of sigma notation looks so difficult ?
Are you saying it only looks difficult? Or it is difficult? Were you able to understand the concept behind sigma?
The sigma notation is easy to understand but the only difficulty is alternating the signs from postive to negative.
Basically to get the signs to alternate you have to multiply by (-1)^n.
Think about it:
and the pattern will just repeat.
So basically its like geometric and arithmetic combine almost?
Yes, some summations may be performed on arithmetic or geometric sequences but this need not always be the case.
I understand what were doing but I'm just confused on how we're substituting, like example 2 confused me with all those exponents and the negatives and positives
Have you tried replaying example 2 and watching it again? Try it, it may help. If not we will look into it more tomorrow.
This is easy to understand some what but i need practice
Great! I look forward to practicing more with you all tomorrow.
this is easy
the ec is n=-2
i mean n=-3
I get it all , I like this new way of learning
I basically get it all, but extra credit got me really thinking, need your help explaining it to me
Sigma Notations make things much easier to understand than normal.
i understand some.. im confuse
I understand this topic
At first that big E looked hard but then u broke down the stels of each piece and then I undeestood it better
i understand it more better
