I wasn't quite sure where to post this but.....
Does anyone know of a good program that will convert vectors from cartesian to spherical or cylinrical. I am (tediously) doing it by hand and would like to check my work.
The current in a 15 millihenry inductor is known to be:
i = 4 amperes, for t < 0 and
i = A1 * e -2000*t + A2 * e -8000*t amperes, for t > 0
The voltage across the inductor (assuming the passive sign convention) is 58 volts at t = 0(+) seconds.
I need to find the constants a1 and a2. I have...
I have this much
Node 1: between the 25k resistor and the 11mA source)
node 2: between the 500 ohm resitor, 10v source, 1k resistor and 500 resistor and the 11mA source
V1: voltage across the 250 resistor
V2: voltage arcross the 1k resistor
reference node at the bottom of the pic
This question may be obvious but I am stumped. I know the definition of a Laplace Transform is integration of e^(-st)f(t). However, I don't know how to integrate with both s and t variables included. If anyone could provide insight I would appreciated it.
