Homework Help: Engineering

Posted by Stuart on Sunday, May 13, 2007 at 1:56pm.

I need help solving the following simultaneous equations, for the values of Vo and a:

1.4 = Vo e^-32a
4 = Vo e^-6a

I've never come across simultaneous equations like this (e is the base of natural logarithms, so perhaps taking logs of both sides might help, but I'm stuck after that).

The second equation:

Vo= 4 e^6a then into the first..
1.4= 4 e^6a e^-32a = 4 e^-26a

From that solve for a by taking the log of each side, then put a back into either side and solve for Vo

Fantastic. Thank you very much!
