The charger with the 900ma output will charge the battery faster than the charger with a 500ma output. The phone with the 900mah battery will last longer between charges than that of the 500mah battery.
F(x + a). If a finite difference is divided by be? A, one gets a difference quotient.
The approximation of derivatives by finite differences plays a central role in finite difference methods for the numerical solution of differential equations, especially boundary value problems.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
