Would all universes have the same prime numbers?

Does the sequence appear to be part of a hidden symmetry?

What does the pattern of prime numbers tell us about infinity?

Let G be a subgroup of some dihedral group. For each x in G, define phi(x) = { (+1 if x is a rotation), (-1 if x is a reflection) }.

How do you prove that phi is a homomorphism from G to the multiplicative group {+1, -1). Also, what is the kernal of phi????

For y = Sin(x), there is no circle with origin (0,0) that can be tangent to the Sin(x) function anywhere locally. For a certain k and greater, a circle with origin (0,0) can be tangent to the Sin(kx) function. What is the minimum value k for which such a circle exists, and what is the diameter of the circle?

Can you please help me understand how the answer of this question is (7π /15)?

The question is: Let R be the region bounded by y=x^2, y=0, and x=1. Compute the volume of the solid formed by revolving R about the line y=1.

I know that V=π (integral sign) A(x)^2 dx.

So I want to set it up as V= π (int) sqrt(x) dx with interval [1,0]. However, it's not working out. Can somebody please enlighten me?

If it asks you to find critical numbers is it [a,b] or (a,b)

Is only (a,b) used for rolle's theorem and mean value theorem?

So if it gives you a function 4/x +x [1,2] find the critical numbers you count 2 as a critical number? If the same equation is used for rolle' theorem you dont count 2?
