How do you find the Average Rate of Change (ARC) of an equation, let's say:
Given f1(x)=-3x^2+12x+3, on x-range:[-1...5] and y-range: [-10...18]...
What is the ARC? Please help I have a test over this Friday!

a cylinder is inscribed inside a sphere with radius R. let x=height of cylinder. write a formila for the volume of the cylinder as a function of x and that includes R in some way. What is the domain of V(x) and graph V(x) when R=3

i have something like pi(4(R^2)-x^2)x/4....is this correct?
im having trouble with the domain and how to get that when we have two variables....

Suppose the sequence of real valued function f_n converges to some f on an interval [a,b] and suppose each f_n is differentiable. I know this doesn't automatically implies f'_n converges to f'. Actually, f'_n doesn't need to converge and, even if it does, it's limit may be other than f'. Is there any theorem which ensures that, under some suitable assumptions, we actually have f' = (lim f_n )' = lim f'_n? Could it's proof be give n here or is it too long for YA?

I know the desired condition is always satisfied by power series. Why? Why are power series so nice, why do they behave so well?

Thank you for your time.
