Alternate series converges
Prove that (1-2) - (1-2^(1/2)) + (1 - 2^(1/3)) - (1 - 2^(1/4)) + ... converges.
Ah, so since (1-2) - (1- 2^(1/2))+... = (-1)(2-1) + (1)(2^(1/2) -1)-... = \sum (-1)^n(2^(1/n)-1). Lim 2^(1/n) = 1 ==> Lim 2^(1/n)-1 = 0. Also, 2^(1/n)>=2^1/(n+1)>=2^(1/n+2)... so {2^(1/n)} is
nonincreasing. Thus ... | 5 | [

Calculating bullet velocity reduction over time
First of all, 1288J is bullet's energy, not force. But, to a good estimate, damage is proportional to energy, so you can use bullet's energy to scale damage. You're on the right track.
The bullet's velocity drops at a rate proportional to vē. In other words, the equation... | 4 | [

Simple quantum problem - find eigenvalues, probabilities, expectation value?
For one thing, your notation is quite inconsistent. You use u for both the given state and the eigenvectors, and then you use a for both the coefficients and the eigenvectors, so I'm not surprised

Some expressions
1. Simplify the expression
(2a^-2-2b^-2)/(4a^-1+4b^-1)
I know it goes to this
(2/a^2-2/b^2)/(4/a+4/b)
I eventually get it down to b-a/2ab
But I guess that's incorrect? I think it ha... | 4 | [

this is the equation
x-y+3z=-4
4x +z=0
x+2y+z=8
I've solved to this point
4x+z=0
4x+z=0
I know this becomes 0=0, but where do I go from here. What would be the solution(s)
