How Do I Denote an Interval of Integration in LaTeX?
Thank you very much! It looks great! I was very surprised this wasn't actually detailed somewhere already. In my searching I also learned about the cancel package, which you can use to show expressions canceling to zero or one or whatever!- omegacore

MATLAB Octave vs Matlab: Will I Run Into Trouble?
/agree with roeb I am only a few hours deep into the Matlab/Octave world and already the ratio is >1. Matlab wins because Octave doesn't have a complete package for controls. Biggest missing tool is the symbolic laplace transform... Its really unfortunate. If I had more time, or didn't have to...- omegacore

What is the validity of the vector identity Ax(BxC)?
Ah yes, I forgot the identifying portion of the identity: Ax(BxC) = B(A dot C) - C(A dot B) Same qualifying question as before. Obviously this identity does not just fall out of the sky and is the product of a process. I am wondering if the process is disrupted (invalid identity) by having...- omegacore

Help with Inductance Homework: Calculate from 84V, 80kOhms & .5355mA
Actually I believe he has his battery voltage right there as Vin. First you got to specify your initial conditions more clearly. Was the inductor attached to the battery prior to t=0 or was the battery connected at t=0? Or was the battery disconnected at t=0? This is important as it will...- omegacore

What is the equation to solve for muzzle speed in a ballistic pendulum problem?
Instead of just applying the formula you might want to consider where the formula comes from. A simple energy relationship will tell you that your square root is in the wrong place. L = L(overall)/2 this is correct.- omegacore
