the problem is: Find real constants A,B, C such that ((1/x^3)-x)=(A/x)+(B/x-1)+(C/x+1).
So A = -1, B = 1/2, C = 1/2

I've heard an urban myth that if your car is stuck somewhere with a dead battery, you cold start rubbing the negative battery post with nylon cloth to build up static electricity that will eventually charge the battery. I'm sure this is remotely true.

But how about one of those survival flash lights that you shake back and forth to generate electricity? If you take the flash light apart and connect the positive from the flash light to the positive of the battery and the negative to negative........ how many days do you think one will have to be standing there shaking the flashlight back and forth in order to charge the car's battery enough to make it spin the starter?
