It kills me when I try to get clever and my signs get skewed.
So, now I've added a couple steps to insure I'm sign-correct and also added the third term to account for the 1's canceling.
Here is the setup:
I = 2.7 (1- \left( 1 +(-0.1) + \frac{(-0.1)^2}{2} + \frac{(-0.1)^3}{6}\right))...
Homework Statement
A resistor and inductor are connected in series to a battery. The current in the circuit ( in A ) is given by I = 2.7(1-e-0.1), where t is the time since the circuit was closed. By using the series for ex, find the first three terms of the expansion of this function.Homework...
