As a South African student, I'm somewhat surprised that this made international headlines. What's more saddening is that the students who made the comment are students of one of the most well respected academic institutions in the country. There is this whole historical reasoning to their...

You need to take into consideration the homogenous part of the equation. Let's take y=yc + yp, why yc is the homogenous part of the equation. You take the annihlator for the right hand side of the original equation and multiply both sides by that, giving you 0 on the right hand side and the...

It would be helpful to have an idea of what level of Calculus and Algebra you need. I can however refer you to a few resources that I find helpful to this day (2nd year Engineering Student). The type of math you can expect: 1) Calculus 1: Differentiation, Basic introduction to Integration...

This problem was very poorly asked then. I get the gist of it now though. Thanks for your help :). Also I drew a few scenarios I had in my head and I better understand what you are saying about the resistors. Once again, thanks for the help :). Much appreciated.

Might be that I'm interpreting it incorrectly. The original question is as follows: "Determine the Thevenin equivalent of the sources and resistor in the circuit." Also, another question I was wondering about was with regard to the Thevenin Resistance. Shouldn't the answer in this case be the...

That was also one of the problems I was facing, the problem itself didn't include the nodes at which the Vth is to be taken. I was going under the assumption that it might be at the voltage source. Is that possible? Can there be a Vth without a voltage source? Sorry about that, I rebuilt the...

Homework Statement I need to find the Thevenin Resistance and the Thevenin Voltage Homework Equations Vth =Rth I (Short Circuit) The Attempt at a Solution I know the answer is supposed to be Rth = 3Ω and Vth = 0.5V, but I couldn't get there with my method. I only get the Rth to be 3 Ω if I...

*Sigh*, I hate the fact that my teachers are so crap. I have to pull through with self studying. Thanks for explaining this to me. Unfortunately, I wasn't really paying attention in class when we were discussing the straight line graph. Also the biggest problem that I have in school at the...

Ah, I see. Thanks for the reply. I thought that it might be so, but I was confused by some other ideas. Like if the container has a hole in it, does that make it harder to increase the pressure inside the container itself? I think I'm beginning to get it now. Would this then be a logical...

Hey guys. I'm new to the forum :). I'm a high school student who takes physical sciences as one of my subject. The thing is that I've been confused about something I read on chemistry. This might sound stupid but please try and understand that this is confusing me. In the gas laws, Gay Lussac's...
