im sry its (n!)^2(a^n) for the numerator

Find the largest value of b that makes the following statement true: "if 0<= a <= b, then the series (from n=1 to infinity) of (((n!)^2a^n)/(2n!)) converges". I know you have to do the ratio test for this one but I don't know how to do it.

If abs x < 1 find a closed form function (i.e. f(x) = x +1) for the following series: \sum((nx)^(2n)) (reads: the series from n=1 to infinity of nx^(2n))

i am just confused because the lower bound is x. I usually deal with the upper bound being x. Does this change the problem? would i get 2/5 u cos(sqrt(5t)) integrated from 6 to x ? do i change cos to sin?

Thanks that is helpful, but i do not know how to apply it. Do you think you can walk me through the problem? I feel I have to see it before I can do it.

would du=5/2u? because i did u^2 = 5t 2udu = 5 du = 5/2u

but how? Should i integrate cos (sqrt(5t)) to 10/3 sin t ^3/2?

Here's the question: integrate the function cos(sqrt(5t)) with lower bound: x and Upper bound: 6

but it does say "A farmer wants to fence an area of 37.5 million square feet in a rectangular field and then divide it in half with a fence parallel to one of the sides of the rectangle."

I don't know. I'm still confused on what the picture will look like. I don't seem to understand.

The problem didn't state any dimensions or equations for the cylinder or cone.

Homework Statement A right circular cylinder is inscribed in a cone with height h and base radius r. Find the largest possible volume of such a cylinder. I'm just really confused on how to figure this one out. The equation for the volume of a cone is v = 1/3pi r^2h and the volume of a...

1. The problem statement A farmer wants to fence an area of 37.5 million square feet in a rectangular field and then divide it in half with a fence parallel to one of the sides of the rectangle. How can he do this so as to minimize the cost of the fence? (Give the dimensions in increasing...

I just use Microsoft Word and that's fine.

Hi! I do not know how to do any of this. Can someone please help me! Thank you. Write the command button Click event procedure from Homework #7 using classes. You should define the class, then write the code contained in the Click event that would use the class. As a reminder, Homework...
