Using the index "n" of the partial sums of a series as the domain, and the value of the corresponding partial sums of the series "Sn" as the range, is a series a function?

Include the following in your answer:

Which one of the basic functions (linear, quadratic, rational, or exponential) is related to the arithmetic series?
Which one of the basic functions (linear, quadratic, rational, or exponential) is related to the geometric series?
Give real-life examples of both arithmetic and geometric sequences and series. Explain how these examples might affect you personally.

F(y) = [(1/y^2) - (3/y^4)] (y+5y^3)

this becomes F(y) = [1(y^-2) - (3(y^-4)] (y+5y^3)

this is what I've solved so far:

F ' (y) = [-2(y^-3)+12(y^-5)] (y+5y^3) + [1(y^-2) - 3(y^-4)](1+15y^2)

I don't know if I've done this correctly at all !!!
The answer should be

F ' (y) = 5 + 14/y^2 + 9/y^4

Could someone please explain this to me. I am struggling taking an online calculus class but I am really making an effort to learn HOW to do the problems. I am just having a hard time with the algebra!

How would you use the product rule to solve this question :

y (x) = (x^2+1)(x^3+1)

is this the next step: (2x)(x^3+1) + (3x2)(x^2+1) ??
I get confused with the algebra after that

the answer is y ' (x) = 5x^4+3^2+2x

but I would like someone to show me how step by step the algebra and did I set it up correctly?

What does 12:00 am and 12:00 pm mean?
And... says who?

As far as I have heard, 12:00 pm can mean midnight but also midday. The same thing for 12:00 am.

I could not find an authority which defines any of those terms. Not even the NIST.
(But I found ISO 8601 which is being used by 95% of the world population.)
